They follow a pattern for valence electrons.
Apex: Representative elements
Representative elements
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.

in the periodic table the rows are called periods and the columns are called groups
The elements located in the first column, group IA on the periodic table, are called alkali metals.

They are called the "alkali metals".
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.
