NEET Chemistry Atomic Radius MCQ Question
Which of the following combinations correctly describe the atomic radius and its behavior in terms of ionic radius?
Cations are larger than their parent atoms, while anions are smaller than their parent atoms.
The atomic radius generally decreases across a period due to increased nuclear charge, and cations are smaller than their neutral atoms.
Anions have a smaller radius than their corresponding neutral atoms due to increased electron repulsion.
Atomic radius increases down a group as additional electron shells are added, and anions are larger than their parent atoms due to electron repulsion.
Correct Answer
Detailed Explanation
Cations are smaller than their parent atoms due to fewer electrons while anions are larger due to increased electron repulsion. The atomic radius indeed increases down a group as additional electron shells are added.
