Question

• What does the principal quantum number
'n' and azimuthal quantum number 'L'
of an electron belonging to an atom
represent?​

Answer 1

Explanation:

principal quantum number determines the size and to a large extent the energy of the orbital it also identifies the shell namely, k(n=1), l(n=2) etc.

azimuthal quantum number is also known as orbital angular momentum or subsidiary quantum number which defines three dimensional shape of the orbital. For a given value of n, l= 0 to n -1.
