Question

When electrons are added in the 6s orbital, what happens to the energy level of the 5d orbitals?

Answer 1

In this condition 6S fill first because

Here the orbit of electrons will be added is to be consider upon the energy level.

It is determine by n+1

n=principal quantum number

L=number of azimuthal quantum

n+1 orbital has low value.

L for s orbital is 0

L for p orbital is 1

L for d orbital is 2

So 6s = 6+0 =6

5d = 5 +2 =7

Based on above assumptions 6S fill first
