Question

n+l Rule... Explain?​

Answer 1

Answer:

In cases where (n + l) is the same for two orbitals (e.g., 2p and 3s), the (n + l) rule says that the orbital with lower n has lower energy. In other words, the size of the orbital has a larger effect on orbital energy than the number of planar nodes.

Answer 2

Orbitals are filled in the order of increasing and n+ l for equal and n + l value the vital with the lower and is most often filled first here and is the principal quantum number and l is the angular momentum quantum number.
