how many orbits, orbitals and electrons are there in an atom having atomic mass 24 and atomic number 12?

Text Solution

Verified by Experts

Atomic number=No. of protons=No. of electrons=12
Electrons configuration=2,8,2
No. of orbits=(K,L and M)
No. of orbitals on which electrons are present
`=(one 1s+ one 2s+three 2p+one 3s).
