Solubility Trends In Group 17 Elements
The affinity of an elements atoms for one another can be quantified using entropy as a unit. For example, it takes less energy to bring gaseous H2S together than gaseous HCl since their molecules are more similar in size.
In contrast, it takes more energy to combine FCl since fluorine has a much smaller electron-cloud diameter than chlorine . By extension, mercury will take even less energy to form alloys with gold or platinum than with iron or nickel because its larger electron-cloud diameter better accommodates them.

Find The Number Of Lone Pairs And Bonded Pair Electrons In The Cl2 Lewis Structure
The lone pair is unshared electrons that not involve in any chemical bonding whereas bonded pair electrons just opposite to it, they have shared electrons that involve in chemical bonding.
As shown in the figure, the Cl2 lewis structure has 1 bonded pair electron in between two chlorine atoms because they are shareable for making the chemical bond.
And 3 lone pairs on each chlorine atom because they are unshared electrons that are not shareable for any type of chemical bonding.
Note: Only a lone pair on the central atom of the molecule considers for finding the geometry of any molecule.
In Cl2, there is no central atom, so the lone pair considered zero for determining its geometry.

What Is The Molecular Geometry Of H2s
The electronic configuration of hydrogen atoms in H2S is
Looking at valence bond theory, we know that a single H atom forms two bonds with each S atom to make a molecule. Each bond contains two electrons, so there are four bonding electrons between H and S atoms. The two lone pairs on each S atom overlap with other teams to form six shared electron pair bonds around a central ionic core or molecule consisting of four ions since S has a valence number +4 one for each pair 2-electron bonds between it and its neighbours.

Lewis Structure Of Chlorine Dioxide
The Lewis structure is a pictorial representation of valence electrons taking part in the formation of bonds to produce a new molecule with new properties altogether.
To begin drawing the Lewis structure of Chlorine dioxide, first, it is essential to draw one for the participating elements.
For Chlorine,
Electronic Configuration = 1s2 2s2 2p6 3s2 3p5
Valence Electrons = 7
Electronic Configuration = 1s2 2s2 2p4
Valence Electrons = 6
Now, it will be easier to draw the Lewis structure of chlorine dioxide as we know that there are 20 valence electrons in one chlorine dioxide molecule.
It might confuse many people as ClO2 comprises 19 valence electrons only.
Here, it is crucial to understand that chlorine dioxide is a strong anion and oxidizing agent.
This arises from the fact that chlorine dioxide is an unstable molecule and mainly exists as ClO2- during bond formation. Due to this, the valence electrons in chlorine dioxide or chlorite are 20.
We will draw the Lewis structure of chlorine dioxide with 20 valence electrons.
Let us follow some steps to draw the Lewis structure of chlorine dioxide:
Step 1: Find the total valence electrons in one molecule of chlorine dioxide.
It is 20 as chlorine has 7 valence electrons and oxygen has 6 valence electrons.
There are two oxygen molecules in chlorine dioxide so the total is 19.
But chlorine dioxide exists as ClO2- during the formation of a bond, therefore we have one more valence electron available.
For Chlorine,
For Oxygen,
Polarity In Chlorine Dioxide
Chlorine dioxide is a polar molecule because it is a strong anion and exists in the ionic form.
It is important to understand that the rule of electronegativity difference will not be applicable in this case.
Although the electronegativity difference between oxygen and chlorine atoms is less than 0.4, chlorine dioxide is a polar molecule which is due to the fact that it is a strong anion.
Let us also check out its properties and uses.

Use Vsepr Chart To Determine The Molecular Geometry Of Cl2
According to Valence shell electron pair repulsion theory if the given molecule has no lone pair on the central atom and has only one bonded pair of electrons, then the molecular geometry of that molecule will be linear and electron geometry will also linear.
In the case of Cl2, there is no central atom, so no lone pair on it, and Cl2 has only one bonded pair of electrons that is between two chlorine atoms.
So, the molecular geometry of Cl2 is linear.
Hybridization In Chlorine Dioxide
From the AXN method, it is clear that the hybridization of chlorine is sp3.
Here it is important to understand that in the case of one more Lewis structure where chlorine and both oxygen atoms are forming double bonds, the hybridization of the chlorine atom will be sp2.
Such a Lewis structure is not a usual case because chlorine dioxide is present in ClO2- form.
In the case of the chlorite ion, mixing and inter-mixing of one 2s and three 2p orbitals takes place to form four new hybrid orbitals of similar energy.
For the sigma bond, head-on overlapping takes place whereas, for the pi bond, lateral overlapping takes place.
Sigma bond is more stable than the pi bond because it undergoes head-on overlapping which is much stronger than lateral overlapping of pi bond.

Why The Molecular Geometry Of Co2 Is Linear
The molecular geometry of CO2 is linear. Because the carbon central atom has no lone pair and is attached to the two oxygen atoms. So, there are two regions of electron density around the carbon central atom, based on VSEPR theory, it will acquire linear molecular geometry.
A region of electron density means the group of bonding or nonbonding electrons that present around the atom.
The single bond, double bond, or even triple bond around the atom will be counted as one region.
The electron pair around the carbon central atom will repel each other and tried to go far from each other, they will take the position where repulsion becomes minimum between them.
According to the VSEPR theory, the central atom with two regions of electron density adopts a linear molecular geometry because repulsion is minimum in electron pairs at this position.
Hence, the molecular geometry or shape of CO2 appears linear.

What Is The Molecular Geometry Of Clo2
The molecular geometry of ClO2 is a bent or V-shape, according to Bristol ChemLabS. ClO2 is the molecular formula for chlorine dioxide. It is a yellowish-green gas that crystallizes to bright orange crystals at -59 degrees Celsius. ClO2 is a potent oxidizing agent used for bleaching and for water treatment.
Chlorine dioxide has an odd number of valence electrons and is considered a paramagnetic radical. The compound is composed of a central chlorine atom with two oxygen atoms connected via covalent bonds. Chlorine dioxide has two resonance structures with a double bond on one side and a single bond and three electrons on the other. Both resonance structures have a bent molecular geometry with an O=Cl-O bond angle of 117.6 degrees. Chlorine dioxide is prepared in a laboratory by the oxidation of sodium chlorite, or NaClO2. CL2 is used as the oxidizing agent, acting on NaClO2 to produce chlorine dioxide and NaCl. Chlorine dioxide is used for the bleaching of wood pulp as an alternative to pure chlorine. Using chlorine dioxide minimizes the amount of toxic organochlorine compounds that are produced as byproducts. For water treatment, chlorine dioxide is less corrosive than chlorine and is more effective at killing certain waterborne pathogenic microbes such as viruses, bacteria and protozoa.
What Are The Electron And Molecular Geometry Of Cl2
The molecular geometry of Cl2 is linear as all diatomic molecules in chemistry have linear geometry because diatomic molecules contain two atoms that are connected with a single bond that produces only a straight line geometry. So, any other geometry is not possible for this type of molecule.
Linear geometry is the simplest arrangement of atoms in a straight line. The electron geometry for Cl2 is also linear. Just remember all diatomic molecule or any molecule that have only two atoms, there geometry or shape will be linear. Thats it.

Stability Of The Periodic Table Trend In Group 17 Elements
One trend in Group 17 elements that stand out among all others is that as you go down a group to a minor feature, regardless of whether it is a halogen or not. This trend can be seen when looking at radii or first ionization energy.
This could be due to an inert pair effect making these elements more stable than those with no idle pairs . With that being said, two exceptions are ICl which has a larger ionic radius than IBr and ICl, which has lower first ionization energy than Br or Cl. These two exceptions can be explained by reasons different from an inert pair effect.
Molecular Geometry & Shape Of Clo2
Lewis structure has a lot of drawbacks even though it is one of the foremost and simplest methods to discuss chemical bonding. It is a 2- dimensional model and does not reflect the molecular design, geometry, or 3- dimensional representation of atoms.
ClO2 has bent molecular geometry. Therefore, chlorine is at the center, and two oxygen surrounds it.
We can also determine ClO2 molecular geometry and shape according to VSEPR theory. For that, we have to use the AXnEx method.
AXnEx notation for acetonitrile molecule:
A is the representation for central atom, so in ClO2, Chlorine atom bonded with two oxygen atoms which mean A = Chlorine
X represents the number of bonded atoms with the central atom, i.e., chlorine atoms bonded to two oxygen atoms and hence n stands for 2.
N represents the total number of lone pairs of electrons present in the central atom. There is two lone pair of electrons present on the central chlorine atom and hence x stands for 2.
Now the generic AXnEx formula for ClO2 molecule will be AX2E2 or AX2E2.
According to VSEPR theory, if the molecule has a generic formula AX2E2 then its molecular geometry will be bent and electron geometry will be tetrahedral.

Molecular Geometry & Shape Of Clo3
Lewis structure has a lot of drawbacks even though it is one of the foremost and simplest method to discuss chemical bonding. It is a 2- dimensional model and does not reflect the molecular design, geometry, or the 3- dimensional representation of atoms.
Now, Valence Shell Electron Pair Repulsion theory suggests an AXE notation.
In AXnEx notation,
A stands for the central atom, here chlorine acts as the central atom.
X represents for the number of surrounding atoms, here three oxygen atoms associated with the center chlorine atom, and hence n stands for 3.
E stands for the number of lone pairs attached to the central atoms, here one lone pairs present on the central chlorine atom, and hence x stands for 1.
Therefore, the ClO3 molecule has AX3E notation. According to VSEPR theory, if the molecule has a generic formula AX2E3 then its molecular geometry will be trigonal pyramidal but electronic geometry will be tetrahedral.

Molecular Geometry Of Clo3
After learning about the hybridization and Lewis structure we can move to the molecular geometry of this compound.
But to properly understand its structure we have to know about the theory which helps us in deciphering the shape of any compound.
This theory is the VSEPR theory.
Lewiss structure tells us about the shape of the compound but only in a 2D perspective.If you want to know about how the compound is going to appear in 3D or a planar representation then we need VSEPR theory.
With the help of the VSEPR theory, we can also find the bond angles and bond length of compounds. Now let us find out the shape of ClO3-, the compound we are learning about.
To find the right shape we will need to take a look at the VSEPR model.
The general formula used here has A, X, and E representation.
Let us put our compound in this formula.
Here, A is Chlorine, X is Oxygen and E is the number of lone pairs on the central atom which in our case is Chlorine.
If we put the values correctly then we see the formula to come at AX3E. See the diagram above and find the shape corresponding to AX3E. It is Trigonal Pyramid.
We can also find the bond angle with the help of this deduction.
The bond angle between oxygen and chlorine atom is somewhere around 109 degrees. This angle is made due to the repulsion between lone pair of electrons and bonded pairs.
Now, as we have learned about the molecular shape of the compound let us move ahead and see what is the polarity of ClO3-.
