Atomic Number - Azimuthal Quantum Number
The number of protons in the nucleus of an atom. This determines an element's structure, properties and location on the periodic table of elements.
One-half the distance between two adjacent atoms in crystals of elements. This varies according to interatomic forces.
The atomic mass of an element divided by its density.
Avogadro, Amadeo (1776-1856)
An Italian chemist who first stated the principle behind stoichiometry in 1811. Also see Avogadro's Number and Molarity, Molality And Normality.
This is the number of atoms in a 12g sample of carbon-12 (C12). This is equal to 6.0221367E23 atoms. It is named for Italian chemist Amadeo Avogadro (1776-1856) who first stated the principle in 1811.
Azimuthal Quantum Number (angular momentum quantum number)
The quantum number that distinguishes orbitals of given n having different shapes. This can be any interger value from 0 to n-1.
