The letters n, l and m proposed by Bohr, Sommerfeld and Zeeman respectivelt for quantization of angular momentum in classical physics were later on obtained as the results of solution of Schrodinger wave equation based on quantum mechanics. The term n, l, m are named as principal quantum number, azimuthal quantum number and magnetic number respectively. The fourth quantum number i.e., spin quantum number (s) was given by Uhlenback on the basis of two spins of electrons. The first two quantum number also decides the nodes of an orbital.
The numerical value `Psi_(4,3,0)` denotes

Options

A. Only n and l decide energy level
B. Only I decides energy level
C. Only n decides energy level
D. n, l and m decide energy level

Answer

C

Explanation

sub -shells of a shell in H-atom possess same energy level, i.e., l does not specify for the energy level of an orbital in H-atom
