The valance electron formation.
Explanation:
elements in the same vertical column also called families or groups have the same number and arrangements of valance electrons.
Group VII A for an example
Fluorine in the second period has seven electrons and a normal charge of -1
Chlorine in the third period has seven electrons has a normal charge of -1 but can also be +1, +3. +5 and +7
This pattern continues for the rest of this vertical family.
