Question

If magnetic quantum number of a given atom is represented by -3 then what will be its principal quantum number?

Answer 1

Dear Student,

Principal Quantum number = n

Azumithal quantum number = l = 0 to n-1

Magnetic quantum number = (2l+1)

Given: l = - 3

-3 = 2l+1
-4 = 2l
l = -2
l = n-1
-2 = n-1
n = 1
