Groups in the periodic table are the vertical columns in which the elements are arranged.
There are 18 groups in the Periodic Table of elements.

groups of the elements
groups are the vertical columns on the periodic table
the answer is groups.Added:There are 18 main groups and two special ones (with 14 lanthanides and 14 actinides respectively).Groups contain elements with the same 'outer' electron configuration (valence electrons).Note: Vertical rows are actually called: columns
It groups elements with similar properties in vertical columns
Columns in the periodic table are called "groups" and there are 18 groups in the periodic table.
The elements that are listed in vertical columns all share specific aspects. These aspects include having the same number of valence electrons and having similar chemical properties.
groups
1) The elements are arranged according to vertical columns.
Columns in a Periodic Table are called groups.They represent elements with similar characteristic. All the elements in a group has same number of valence electron.
