Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.

∙ 11y agoThe term "main group" elements has been a term used to describe the elements in groups 1,2, and 13 through 18 of the modern Periodic Table.
In the older versions of the periodic table it was groups IA, IIA, but there was an ambiguity in which of the other pairs of groups were labelled A or B.
So the "main group" elements are those in families with Na, Mg, Al, Si, P, S, Cl, & Ar.

What is in the main group of elements?
The main group of elements includes all the elements in columns 1, 2, and 13 through 18 of a wide form periodic table. All the other elements are "transition elements", and those in the two horizontal rows at the bottom of a wide form periodic table are also called "inner transition" elements.
