Answer

Brief Explanations:

For Question 10: Atomic radius generally decreases across a period. Chlorine (Cl) and Argon (Ar) are in the same period. Cl is a non - metal that forms anions by gaining electrons and Ar is a noble gas. The atomic radius of Ar is smaller than Cl due to effective nuclear charge. For Question 11: When an atom gains electrons to form an anion, the electron - electron repulsion increases and the radius of the anion is larger than the parent atom. So, S²⁻ has a larger radius than S.
