Explanation:
Detailed explanation-1: -Summary. The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.
Detailed explanation-2: -The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Detailed explanation-3: -Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.
