They follow a pattern for valence electrons.
The elements in the A columns of the periodic table are called representative elements or main group elements. They are grouped into families based on similar chemical properties and valence electron configurations.

The vertical columns are referred as noble elements. They are also called inert elements.

They follow a pattern for valence electrons.
Conventionally representative elements are called the chemical elements from the groups 1,2, 13-18. These elements haven't generally variable valencies. The transitions metals are not representative elements.

The columns are called groups (or, sometimes, families). The rows are called periods.
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
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.
