Question

Explain the inter relation between the quantum numbers

Answer 1

Quantom number is a physical quantity.........

Answer 2

There are four quantum numbers which can describe an electron in an atom completely.

1. The Principal Quantum Number(n): It describes the electron shell,energy level of an atom.The value of n=1,2,3,4,.......
2. The Azimuthal Quantum Number(l): It is known as the angular or orbital quantum number.It describes the subshell and gives the magnitude of the orbital angular momentum.The value of angular momentum=0,1,2,3,......,(n-1)
3. The Magnetic Quantum Number(ml): It describes the energy level available within a subshell and yield the projection of the orbital angular momentum along a specified axis.The value of ml= -l,....,-1,0,1,...,l

The Spin Projection Quantum Number(ms): It describes intrinsic angular momentum of the electron  within that orbital and gives the projection of the spin angular momentum along the specified axis.The value of ms=+1/2,-1/2
