Answer:

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.

Explanation:

All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.

The groups in periodic table are vertical columns in which elements with similar properties and same number of valence electrons are classified together.

In periodic table, all elements are classified into different periods and groups. The vertical columns in the table is called groups and the horizontal rows are called periods.

The elements in a group have same number of valence electrons and similar chemical and physical properties. For example lithium  and sodium are first group elements and they show similarity in properties.

There are 18 groups and 7 periods in periodic table. The first two groups are pure metals. Groups from 3-12 are called transition metals. 13 to 18 group elements are nonmetals.
