A vertical column is called a 'group.' A horizontal row is called a 'period,' thus the periodic table.
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 .
Representative elements
groups
All of the elements are on the periodic table of the elements. Refer to the related links for a printable periodic table.
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.

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.
