Question

Element having atomic number 33 belongs to this group?

• A. III
• B. IV
• C. V
• D. VI

Answer 1

The correct option is C V

Electronic configuration of element with atomic number 33 is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^3$. So, it is a p-block element with 3 electrons in p orbital, therefore it lies in 5 A group or 15 group.
