What could be done to change this carbide ion to a neutral carbon atom? remove 2 electrons add 2 electrons remove 4 electrons add 4 electrons

To change a carbide ion to a neutral carbon atom, the four valence electrons must be removed.

A carbide ion is a negative ion with a negative charge of 4 often written as . To attain a neutral state, a carbide ion usually combine with a metal to form a metallic carbide.

During the reaction process, since a carbide ion has four valence electron in excess, to become neutral it must loss or share the 2 pairs of the electrons with a metal, giving rise to the metallic carbide.

The basic properties of carbides include the following;

Thus, to change a carbide ion to a neutral carbon atom, the four valence electrons must be removed.
