How many unpaired electrons are in calcium?

Answer 1

There are no unpaired electrons in calcium, all 20 electrons are in pairs, i.e. each pair is configured in one orbital:

2x in 1s orbital

2x in 2s orbital

2x in each of the three 2p orbitals

2x in 3s orbital

2x in each of the three 3p orbitals

and

2x in 4s orbital (these two are the valence electrons)

Answer 2

There are no unpaired electrons in calcium. There are two electrons in the 4s sublevel. Calcium will lose those two electrons in order to form ionic compounds with nonmetals like oxygen and chlorine.

Answer 3

There are 0 unpaired electrons in a neutral calcium atom. Calcium has an atomic number of 20, meaning it has 20 electrons arranged in orbitals. The electron configuration of calcium is 1s2 2s2 2p6 3s2 3p6 4s2, indicating that all its electrons are paired.
