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

A carbide ion is an anion of carbon atom with two carbon atoms with a triple bond connected to each other. Since this carbide ion is a negatively charged ion, in order to convert carbide ion to its neutral carbon atom, it has to give up/remove four 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;

they are good conductors of heat.they are good conductors of electricitythey have high melting point.

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