Answer
Elements found in in the same vertical columns (Group 1A, 2A, etc) will share common properties. In the periodic table, the vertical columns of elements are called groups, or families.
Explanation
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. The horizontal rows on the periodic table are called periods.
Hence, elements found in in the same vertical columns (Group 1A, 2A, etc) will share common properties. In the periodic table, the vertical columns of elements are called groups, or families.
