Problem: Determine whether or not each element is a main-group element.vanadium

We’re asked to determine whether or not vanadium is a main-group element.

Recall that the main group elements belong to the s- and p-blocks in the periodic table. 

Main group elements form charges that are the same as their group number and are usually found in Groups ending in A in the periodic table:

• Main Group metals → Groups 1A, 2A (some in 3A such as Al)
• Main Group nonmetals → Groups 3A to 8A

We will determine whether Vanadium, V is a main group element based on the periodic table of elements:
