If the atomic number of an elements is 33, it will be place in the periodic tabe in the

A

first group

B

fifth group

C

third group

D

seventh group

Text Solution

Verified by Experts

The correct Answer is:
B
`33:1s^(2),2s^(2).2p^(6),3s^(2),3p^(6),4s^(2),3d^(10),4p^(3)` it its valence shell `5underset(bar)(e)^(-)` are present so it is fifth (A) group elements.
