Which of the following options explain why cations are smaller and anions larger in radii than their parent atoms?

Options

1. ACations have fewer protons, resulting in a smaller effective nuclear charge, while anions have more protons, l
2. BCations have gained electrons, resulting in a smaller electron cloud, while anions have lost electrons, leadin
3. CCations have lost electrons, resulting in a smaller electron cloud, while anions have gained electrons, leadin
4. DCations and anions have the same number of electrons, but cations have a smaller number of protons in the nucl
