Question

If p-orbitals start from the first shell then what will be the number of elements in third period of periodic table?​

Answer 1

Answer:

then in second shell there will be d orbitals and it accomodates 10 electrons

Explanation:

s Orbital :2 electrons

pOrbital:6 electrons

d orbital:10

f orbital : 14

Answer 2

Answer:

If p orbitals start from the first shell then the third period of the periodic table would consist of 18 elements. As the elements would begin filling the d orbitals in the third period which would give rise 18 elements in the third period.

I suppose this is the answer I'm not sure.
