Understand that the periodic table is organized in two main directions: horizontally and vertically.
The horizontal rows in the periodic table are called 'Periods'.
The vertical columns in the periodic table are called 'Groups'.
Groups are also sometimes referred to as 'Families' because elements in the same group often have similar chemical properties.
Therefore, the term used to refer to the columns in the periodic table is 'Groups' (or 'Families').
