when electrons are added to the outermost shell of a carbon atom, it forms\nan anion that has a larger radius.\nan anion that has a smaller radius.\na cation that has a larger radius.\na cation that has a smaller radius.

when electrons are added to the outermost shell of a carbon atom, it forms\nan anion that has a larger radius.\nan anion that has a smaller radius.\na cation that has a larger radius.\na cation that has a smaller radius.

Answer

Brief Explanations:

When electrons are added to an atom, it forms an anion. The added electrons increase electron - electron repulsion and the effective nuclear charge on each electron decreases, causing the electron cloud to expand and the radius to increase.

Answer:

an anion that has a larger radius.
