The columns tell you how many electrons the atoms have in their outer shells, which is a very essential information to understand reactions. Group 1 has 1 electron in the outer shell, group 2 has 2 electrons, etc.
The columns are called groups (or, sometimes, families). The rows are called periods.
The columns in the periodic table are called groups or families. These columns contain elements with similar chemical properties due to their shared number of valence electrons.
