Answer:

an anion that has a larger radius.

Step-by-step explanation:

When a neutral atom gains electrons it forms an anion, and when it loses electrons it forms a cation. The radius or size of an anion is greater than a neutral atom. The radius or size of an cation is smaller than a neutral atom.

When electrons are added to the outermost shell of a carbon atom, it forms an anion that has a larger radius.
