Question

the n+l value of 3p energy level is
step by step explaination.​

Answer 1

Answer:

the n+l value of 3p she'll is 3+1=4

hope it help you

Answer 2

The (n+l) rule is given by Afbau. The principal states that orbitals are filled up in order of increasing energy. The orbital of lowest energy is filled first. The energy sequence is decided by (n+l) rule.

The orbital with higher value of (n+l) has higher energy. If the (n+l) values are same , the orbital with higher value of (n) has higher energy.

the energy sequence is,

1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s<5f<

6d

For 3p orbital

n=3 and l=1

(n+l) value= (3+1)=4

note: n= principal Quantum number

l=Azimuthal Quantum number.
