Calcium has 20 protons and 20 electrons. When we fill in the first 20 orbitals, we get the configuration of 1s2 2s2 2p6 3s2 3p6 4s2. Since 4 is the outermost shell in this configuration, calcium has 2 valence electrons.

Depends on what you mean by number of electrons. Calcium has 20 electrons and oxygen has 8 electrons for a total of 28 electrons. But if you mean how many VALENCE electrons, then the calcium has 2 and the O has 6 for a total of 8 valence electrons.
