The Correct Option is C

Solution and Explanation

The stability of higher oxidation states decreases down the group due to inert pair effect. Hence, bismuth pentoxide which is obtained by the action of strong oxidizing agents on $ B{{i}_{2}}{{O}_{3}}, $ is extremely unstable and loses oxygen to form trioxide. Therefore, $ Bi $ does not form $ B{{i}_{4}}{{O}_{10}}. $ .

Group 15 Elements

Group 15 elements are also known as nitrogen group elements or nitrogen family

It consists of:

  • Nitrogen (N)
  • Phosphorus (P)
  • Arsenic (As)
  • Antimony (Sb)
  • Bismuth (Bi)
  • Moscovium (Mc)

They are present on the right side of the periodic table. All the elements are arranged based on their atomic weight. The elements with similar properties reside in a column called the group.

All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is the principal quantum number.
