How are the groups organized in the periodic table? What do all the elements in a group have in common?

Respuesta :

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.

elements from each group have the same numbers of electrons in the outer orbital, valence electrons are involved with chemical bonds with other elements.
