The number of protons in the nucleus of an atom. In electrically neutral atoms, this number is also equal to the number of electrons orbiting about the atom's nucleus. The atomic number of an element determines its position in the Periodic Table. ...
Chemical elements are made up of only one type of atom—gold contains only gold atoms, and neon contains only neon atoms--and they are ranked in order of their atomic number (the total number of protons in its nucleus) in a chart called the periodic table. Accordingly, because an atom ...
In order to assign oxidation numbers to atoms, we need to follow a set of rules. This video cannot be played because of a technical error.(Error Code: 102006) 1. The oxidation number of an element in its free state is zero. Example: The oxidation number of Zn, Al, H2, O2, and Cl...
Avogadro's Constant defines the number of particles in one mole, making it fundamental in relating mass to the number of atoms or molecules. 9 Is Avogadro's Number still relevant in modern chemistry? Yes, Avogadro's Number is still used for its simplicity and historical significance, especially...

The periodic table is a chart that shows how chemical elements are related to each other. Elements with atomic numbers 58 through 71 are known as the lanthanides. The name comes from the element lanthanum. The lanthanides are also known as rare earth elements. Although lanthanides are not ...
Atomic mass is expressed in atomic mass units (amu) for a single atom and in grams per mole for macroscopic quantities. A mole is quantified as Avogadro's number (6.02 × 1023) of atoms. An atom of a given element always has the same number of protons. If it had a different number,...
