Question

what is the lowest shell are present in 4d orbital​

Answer 1

Answer:

Correct option is

C

5p

After filling the 4d-orbital, an electron will enter in 5p orbital.

The 4d sub-energy level is at a lower energy than the 5p sub-energy level

For 4d, n=4 and l=2.  Hence, (n+l)=4+2=6

For 5p, n=5 and l=1.  Hence, (n+l)=5+1=6

As the value of (n+l) for 4d orbital is same as that of 5p orbital, 4d orbital is filled before 5p orbital as 4d orbital has lower value of n than 5 p orbital.

Note: If two orbitals have same value of (n+l), then the orbital with lower value of n will be filled first.
