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.
What are groups in periodic table ?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.
