Question

which of the following statements correctly compares the relative size of an ion to its neutral atom? the radius of an anion is greater than the radius of its neutral atom the radius of an anion is identical to the radius of its neutral atom the radius of a cation is greater than the radius of its neutral atom the radius of a cation is identical to the radius of its neutral atom

Explanation:

An anion is formed when a neutral atom gains electrons. The added electrons increase electron - electron repulsion, causing the electron cloud to expand and making the anion larger than the neutral atom. A cation is formed when a neutral atom loses electrons. With fewer electrons, the remaining electrons are pulled closer to the nucleus, making the cation smaller than the neutral atom.

Answer:

the radius of an anion is greater than the radius of its neutral atom
