In periodic table the horizontal rows are called periods and the vertical column are called group.
The elements placed on the left of the table are metals which contain its last electron on s-orbital hence considered as s-block elements and the elements placed on the right side of the table contains its last electron in p-orbital which is regarded as p-block elements.
The s and p block elements together are called as main group elements.
Nonmetals: The right of diagonal elements stretches from boron to Tellurium, in group 14 to 18.
Main group elements are included from group 1A to 8A.
Lanthanides are 6th period elements from lanthanide to hafnium.
Actinides are 7th period elements from actinium to lawrencium.
