The periodic table is organized into groups (columns) and periods (rows).

Explanation:

The periodic table is organized into groups (columns) and periods (rows). The first ones contain those elements that have the same valence and have similar characteristics to each other. Example: group IA have valence 1 (they require 1 electron to reach the octet). The exception to this are the noble gases located in the last group to the right of the table, which have already filled their last energy level.

Periods have elements that have the same number of orbitals and have different properties; although the masses are similar.
