Question

maximum number of Orbital n+l = 5​

Answer 1

n can take values like 1,2,3..

l can take values from 0 to (n-1)

This means l can’t be greater than n.

Now lets look at all the possible combinations to get n+l=5

They would be-

n=3 l=2

n=4 l=1

n=5 l=0

Now lets look at all cases one by one -

n=3 , l=2

it would mean 3d orbital which can accomodate maximum 10 electrons.

Similarly ,

n=4 , l=1

Max. electrons=6

n=5 , l=0

Max. electrons=2

Total adds up to 18.

Hope it helps. :)

Answer 2

Answer:

6

Explanation:

Orbitals : 1s, 2s, 2p,3s, 3p, 4s (n+l) value: 1 , 2 , 3 , 3 , 4 , 4.
