Vertical column on the periodic table is called a

Explanation:
A vertical column on the periodic table is a group. Elements in the same group share similar chemical properties because they have the same number of valence electrons, which governs how they bond and react. The horizontal rows are called periods, reflecting the increasing atomic number and the filling of electron shells. Sometimes people use the term family as well, but group is the standard term. For example, the first vertical column contains the alkali metals, all with one valence electron and high reactivity.
