how many valence electrons does a neutral atom of carbon have?

A neutral atom of carbon has 4 valence electrons.

Quick Scoop

• Carbon’s atomic number is 6, so it has 6 electrons in total.

• Its electron configuration is 1s2 2s2 2p21s^2,2s^2,2p^21s22s22p2, meaning there are 4 electrons in the outer (second) shell.

• Those 4 outer-shell electrons are the valence electrons, which is why carbon can form 4 covalent bonds (it is tetravalent).

In simple terms: carbon’s outer shell holds 4 electrons, so a neutral carbon atom has 4 valence electrons.
