Question

Write the significance of the following;
(i) (n+l) rule
(ii) Heisenberg’s uncertainty principle
. (iii) Magnetic quantum number

Answer 1

Explanation:

1....the N+L rule tells us about the energy of the orbital. If n+l value is more then it means that it's energy is more, and vice versa ..

2.... Heisenberg s uncertainty tells us that position and momentum of an electron cannot be simultaneously determined.

I.e,, ∆x × ∆p is always greater than or equal to h÷4π..

3.... magnetic quantum number helps us in determining the orientation of an orbital...

magnetic quantum number always is between the max l(azimuthal quantum no) to minimum l( azimuthal quantum no)
