Question

How manyelectrons are therein the third shell (principal energy level) of the atom with atomic number23

Answer 1

Answer:

actually principal energy level is 8 in the third shell

Explanation:

but actually 18 is given for the third shell but oske liye bhute energy chahiye jo heat karke hi milegi.

Answer 2

Answer:11

Explanation:

If you know the concept of orbitals and quantum numbers, then the answer is as follows

Electronic configuration of at.no.23

1s2 2s2 2p6 3s2 3p6 4s2 3d3

In third shell total no of electrons=2+6+3=11
