When 4p orbital in any atom is filled completely,the next electron goes in

A

5s

B

3d

C

4d

D

4f

Text Solution

Verified by Experts

The correct Answer is:
a
According to the Aufbau principle and (n+1) rule, the orbitals with increasing order their energies is as follows,
Is`lt2slt2plt3s lt3plt4slt3dlt4plt5s....`
Therefore, after 4p orbital is completely filled,the next electron goes in 5s orbital.
