A vertical column is called a 'group.' A horizontal row is called a 'period,' thus the Periodic Table.

groups or family:))
In the periodic table a column is the elements that go down the way.for exampleLiNaKRbCsFrThis is a column and called the Alkali metals. Group 1.A period is when it goes across.
Elements are organised in terms of properties in same column. Properties are found to be periodic .
Elements in the same column of the periodic table are called "groups" or "families". They share similar chemical properties due to having the same number of valence electrons, which influences their reactivity and behavior.
Representative elements
groups
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
iDkkk Lmaoo !!

Yes, it is.
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
Each column is a group of chemical elements.
