Apply the rule of the periodic table to your element. The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. Each new period begins with one valence electron. Exclude groups 3 through 12.

WebValency. The periodic table’s valency increases and eventually drops over a time period. The heavier elements (those with an atomic number greater than 20), particularly the lanthanide and actinide series, follow this periodic trend less frequently. More core electrons cause better shielding of electrons from the nucleus’s core charge.
