Detailed Solution

30 protons corresponds to atomic number 30 and 30 electrons.
It is atomic number of Zn. Its electronic configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 .

Out of this, the electrons and orbitals with m=0 are 1s2 2s2 2px2 3s2 3p2​ 4s2 3d2 .

Total number of such electrons =2+2+2+2+2+2+2=14.

Thus, there are 7 orbitals and 14 electrons from m = 0, if there are 30 protons in an atom.
