Another name for the columns in the periodic table is "groups." These groups are numbered from 1 to 18, and each group shares similar chemical properties due to the arrangement of electrons in their outer energy levels.
Groups of the Periodic Table are defined as vertical colums. There are 18 groups in the periodic table.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.

a group
The columns on a periodic table are called "groups" or "families." Groupings are based on the number of valence electrons elements within the same group have in common, which influences their chemical properties.

Not all, but some Groups/Vertical columns have their own name. Group (I) ; Alkali Metals. Group(II) ; Alkaline Earth Metals. Group(VII) ; The Halogens Group (VIII) ; The Noble or Inert Gases.
The middle 10 columns of the periodic table are known as the transition metals. These elements are characterized by their ability to form colored compounds and exhibit variable oxidation states. They are located between groups 3 to 12 on the periodic table.
