both valence and nonvalence electrons.
None of the above.

Answer 1

In a double covalent bond, a carbon atom shares **two electrons**. Therefore, the correct answer is **two electrons**.

In a double bond, there are typically two shared pairs of electrons between two atoms, but in the context of your question, it's the sharing of two electrons (one pair) that is highlighted.
