Key Takeaways: Chemical Element Definition
- A chemical element is a substance that cannot be further broken down by any chemical reaction.
- Each element has a unique number of protons in its atom. For example, a hydrogen atom has 1 proton, while a carbon atom has 6 protons.
- Varying the number of electrons in an atom of an element produces ions. Changing the number of neutrons produces isotopes.
- There are 118 known elements.

Parent And Daughter Isotopes
When radioisotopes undergo radioactive decay, the initial isotope may be different from the resulting isotope. The initial isotope is called the parent isotope, while the atoms produced by the reaction are called daughter isotopes. More than one type of daughter isotope may result.
As an example, when U-238 decays into Th-234, the uranium atom is the parent isotope, while the thorium atom is the daughter isotope.
A Note About Stable Radioactive Isotopes
Most stable isotopes don’t undergo radioactive decay, but a few do. If an isotope undergoes radioactive decay very, very slowly, it may be termed stable. An example is bismuth-209. Bismuth-209 is a stable radioactive isotope that undergoes alpha-decay but has a half-life of 1.9 x 1019 years . Tellurium-128 undergoes beta-decay with a half-life estimated to be 7.7 x 1024 years.

Why Does Water Have A High Specific Heat
It is because of the hydrogen bonds. It fact, it is the highest S.H. of all liquids. Because water is a polar molecule, with a large electronegativity difference between hydrogen and oxygen, hydrogen bonds form between the positive hydrogen atoms in one molecule, and the negative oxygen atoms in nearby molecules. It takes a lot of energy to loosen and break the hydrogen bonds between water molecules. This is the reason that oceans cool down slower than land does.

Heat Capacity Of Water
The S.H capacity of water is associated with the unit called the calorie. In fact, one calorie is defined as the amount of heat need to raise 1 gram of liquid water one degree Celsius. The calorie was first used by Nicolas Clement in the early 19th century. It comes from the Latin word calor meaning heat.

What Is The Difference Between Suspension And Colloid
Unlike colloid particles, those in a suspension can be separated by filtration. Colloids are capable of scattering light, but suspensions are not. Particles in a suspension can be seen with the naked eye, but those in a colloid require the use of a light microscope.

Glossary Of Chemistry Terms
|Part of a series on|
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions it features an extensive vocabulary and a significant amount of jargon.
Note: All periodic table references refer to the IUPAC Style of the Periodic Table.
- absolute zero
- A theoretical condition concerning a system at the lowest limit of the thermodynamic temperature scale, or zero kelvins, at which the system does not emit or absorb energy . By extrapolating the ideal gas law, the internationally agreed-upon value for absolute zero has been determined as 273.15 °C .
- 1. The physical or chemical process by which a substance in one state becomes incorporated into and retained by another substance of a different state. Absorption differs from adsorption in that the first substance permeates the entire bulk of the second substance, rather than just adhering to the surface.
- 2. The process by which matter takes up the energy of electromagnetic radiation and transforms it into any of various types of internal energy, such as thermal energy. This type of absorption is the principle on which spectrophotometry is based.

Extension Of The Symbol
In addition to the letters for the element itself, additional details may be added to the symbol as superscripts or subscripts a particular isotope, ionization, or oxidation state, or other atomic detail. A few isotopes have their own specific symbols rather than just an isotopic detail added to their element symbol.
Attached subscripts or superscripts specifying a nuclide or molecule have the following meanings and positions:
A list of current, dated, as well as proposed and historical signs and symbols is included here with its signification. Also given is each element’s atomic number, atomic weight, or the atomic mass of the most stable isotope, group and period numbers on the periodic table, and etymology of the symbol.
Discovery And Recognition Of Various Elements
Ten materials familiar to various prehistoric cultures are now known to be chemical elements: Carbon, copper, gold, iron, lead, mercury, silver, sulfur, tin, and zinc. Three additional materials now accepted as elements, arsenic, antimony, and bismuth, were recognized as distinct substances prior to 1500 AD. Phosphorus, cobalt, and platinum were isolated before 1750.
Most of the remaining naturally occurring chemical elements were identified and characterized by 1900, including:
Elements isolated or produced since 1900 include:
- The three remaining undiscovered regularly occurring stable natural elements: hafnium, lutetium, and rhenium
- Plutonium, which was first produced synthetically in 1940 by Glenn T. Seaborg, but is now also known from a few long-persisting natural occurrences
- The three incidentally occurring natural elements , which were all first produced synthetically but later discovered in trace amounts in certain geological samples
- Four scarce decay products of uranium or thorium , and
- Various synthetic transuranic elements, beginning with americium and curium

C + O2 Is Equal To C + O How Is That Possible
C + O = CO2 . This is because carbon has valency of 4 while oxygen has valency of 2. When they react the valencies are criss crossed which means we will get C2O4 but this is simplified to CO2.
But my textbook say that C + O2 = CO2.
So how is it possible that C + O2 and C + O both get the same product of CO2?
Also you can say that the reaction of C + O = CO2 is not balanced but the balanced chemical reaction would be C + 2O = CO2 not C + O2 = CO2 which is the reaction that my textbook says.

He assumed that:
Origin Of The Elements
Only about 4% of the total mass of the universe is made of atoms or ions, and thus represented by chemical elements. This fraction is about 15% of the total matter, with the remainder of the matter being dark matter. The nature of dark matter is unknown, but it is not composed of atoms of chemical elements because it contains no protons, neutrons, or electrons. .
The 94 naturally occurring chemical elements were produced by at least four classes of astrophysical process. Most of the hydrogen, helium and a very small quantity of lithium were produced in the first few minutes of the Big Bang. This Big Bang nucleosynthesis happened only once the other processes are ongoing. Nuclear fusion inside stars produces elements through stellar nucleosynthesis, including all elements from carbon to iron in atomic number. Elements higher in atomic number than iron, including heavy elements like uranium and plutonium, are produced by various forms of explosive nucleosynthesis in supernovae and neutron star mergers. The light elements lithium, beryllium and boron are produced mostly through cosmic ray spallation of carbon, nitrogen, and oxygen.
In addition to the 94 naturally occurring elements, several artificial elements have been produced by human nuclear physics technology. As of 2021, these experiments have produced all elements up to atomic number 118.

Symbols For Named Isotopes
The following is a list of isotopes of elements given in the previous tables which have been designated unique symbols. By this it is meant that a comprehensive list of current systematic symbols is not included in the list and can instead be found in the Isotope index chart. The symbols for the named isotopes of hydrogen, deuterium , and tritium are still in use today, as is thoron for radon-220 . Heavy water and other deuterated solvents are commonly used in chemistry, and it is convenient to use a single character rather than a symbol with a subscript in these cases. The practice also continues with tritium compounds. When the name of the solvent is given, a lowercase d is sometimes used. For example, d6-benzene and C6D6 can be used instead of C6.
The symbols for isotopes of elements other than hydrogen and radon are no longer in use within the scientific community. Many of these symbols were designated during the early years of radiochemistry, and several isotopes bear placeholder names using the early naming system devised by Ernest Rutherford.

Chemically Pure And Isotopically Pure
Chemists and nuclear scientists have different definitions of a pure element. In chemistry, a pure element means a substance whose atoms all have the same atomic number, or number of protons. Nuclear scientists, however, define a pure element as one that consists of only one stable isotope.
For example, a copper wire is 99.99% chemically pure if 99.99% of its atoms are copper, with 29 protons each. However it is not isotopically pure since ordinary copper consists of two stable isotopes, 69% 63Cu and 31% 65Cu, with different numbers of neutrons. However, a pure gold ingot would be both chemically and isotopically pure, since ordinary gold consists only of one isotope, 197Au.
