atomic number
... nucleus of an atom is called the atomic number. For example, any atom with 6 protons in the nucleus is a Carbon atom. • Elements are arranged in the periodic table by their atomic number. • In a neutral atom, # electrons = #protons. • The symbol for an element is simply its 1, 2, or 3 letter abbrevi ...
