Members of the same group on the periodic table have the same number of _____

Explanation:
Valence electrons are the outer electrons that participate in bonding. In a column of the periodic table, elements have the same number of valence electrons, so they exhibit similar chemical behavior and bonding patterns. The numbers of protons, neutrons, and inner-shell electrons can vary as you move down a group, but the outer-electron count stays the same, which is why members of a group act alike. That shared outer-electron count is the reason why valence electrons are the correct attribute to compare.
