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.

Formal Charges And Octet Rule:
Distinctive Lewis structures are feasible for an atom however the steadiest one is viewed as which observes the rule, with least partition of charges. One factor might overwhelm over the other for specific atoms.
For BrO3BrO3 Br has 7 valence electrons, and O has 6. The conceivable Lewis structure which observes octet rule is:
In this design, the conventional charges are raised, Br has +1 formal charge, 2 of the O iotas have – 1 proper charge.
Another conceivable design what disrupts the octet guideline yet limits formal charges is:
Here, Br has 0 proper charge and just a single O has – 1. The octet rule isnt followed as Br has 12 electrons here rather than 8.

What Is Vsepr Of Bro3
It’s electron geometry is tetrahedral but it’s molecular geometry is pyramidal. Bond angles are less than 109.5 degrees. Because of the unpaired electrons , it is polar. Partial positive charges on the bromine with unpaired electrons, and partial negative on the oxygen bonds. Central atom hybridization=sp3. For a picture, I would suggest an internet search for VSEPR AB3E.Make the Lewis Dot structure and you will see that one pair of electrons is non-bonding. The repulsion between electron pairs is strongest between two non-bonding PAIRS of e-. But, the next strongest repulsion is between a bonding pair and a non-bonding pair. In the case of BrO3, the non-bonding pair is surrounded by two bonding pairs of e-. That is why the model shows the bonds angling away and down from the central atom instead of straight out.Draw an arrow up from the Br atom through the non-bonded pair of e- to represent the most repulsive pair of e-. This is the “E” in AB3E.Draw arrows out through the other 3 bonded pairs of e- and make them a little shorter to remind you why this molecular geometry is pyramidal in shape rather than merely tetrahedral. You should have 4 arrows pointing away from the Br one bigger than the other three to represent the unbonded e-.
Check The Stability And Minimize Charges On Atoms By Converting Lone Pairs To Bonds
