Understand the structure of the periodic table: it is arranged in rows and columns.
Rows in the periodic table are called 'Periods' and represent elements with the same number of electron shells.
Columns in the periodic table are called 'Groups' or 'Families' and contain elements with similar chemical properties due to having the same number of valence electrons.
The term 'Blocks' refers to sections of the periodic table based on electron subshells (s, p, d, f), not columns.
Therefore, the correct term for the columns on the periodic table is 'Groups'.
