When electrons are added to the outermost shell of a carbon atom, it forms an anion that has a larger radius. An anion always has a larger radius than a neutral atom of the same element. This is because more electrons cause greater repulsion between its nucleus and electrons, making the electrons move farther away from the center.

Explanation:
Electron affinity is the change in energy when a neutral atom in its gaseous form gains an electron to form a negative ion. For example, when a neutral fluorine atom in its gas state gains an electron, it releases energy to form a fluoride ion.
