Question

Considering Strontium (Sr) is in ground state, what possible number of electrons would be in orbitals that are spherical.

Answer 1

Electron configuration for a neutral strontium atom in its ground state is;

$Sr:\textcolor{blue}{1s^2}\>\textcolor{blue}{2s^2}\>2p^6\>\textcolor{blue}{3s^2}\>3p^6\>\textcolor{blue}{4s^2}\>3d^{10}\>4p^6\>\textcolor{blue}{5s^2}$

10 electrons will be in orbitals that are spherical
