Question

Which of these subshell designations are possible and which are impossible?

 

Answer 1

for 3d:

n=3

l=2

This is possible

for 0p:

n=0

l=1

n must be a positive number

n can't be 0

Hence, this is not possible

for 2d:

n=2

l=2

l must be less than n

Here value of n is 2

But value of l is 2

so, l can't be 2

Hence, this is not possible

for 3f:

n=3

l=3

l must be less than n

Here value of n is 3

But value of l is 3

so, l can't be 3

Hence, this is not possible

for 2p:

n=2

l=1

This is possible
