What are the columns of the periodic table called

A) Rows

B) Groups

C) Elements

D) Periods

Correct Answer:

B) Groups

Explanation:

In the periodic table, the vertical columns are called “groups” or “families.” Each group contains elements with similar chemical properties because they have the same number of valence electrons, which influences their reactivity and chemical behavior. Rows in the periodic table are called “periods,” and they represent the arrangement of elements by increasing atomic number.
