Question

Principal quantum number related to energy of an electron

Answer 1

Answer:

the answer is explained below

Explanation:

Energy of an orbital can be compared using (n + l) rule

if the azimuthal quantum number is same, then the orbital having greater n(principal quantum number)

value has greater energy .

Energy of a electron is proportional to Z²/n²

where Z : atomic number

and n : is the orbit of the electron
