Question

Quizplus · Accepted Answer

When an atom gains an electron, it becomes negatively charged, which means it has more electrons than protons. Such a particle is called an anion. Option A is incorrect because a proton is a positively charged particle found in the nucleus of an atom, and gaining electrons does not result in the creation of a proton. Option C is incorrect because a cation is a positively charged particle formed when an atom loses electrons, not gains it. Option D is incorrect because an isotope is an atom that has the same number of protons but a different number of neutrons than other atoms of the same element. Option E is incorrect because one of the options is correct.
