Answer

Explanation:

Step1: Recall atomic - radius trend

Atomic radius increases down a group and decreases across a period from left - to - right.

Step2: Locate elements on periodic table

Silicon (Si) is in Group 14 and Period 3. Aluminum (Al) is in Group 13 and Period 3. Carbon (C) is in Group 14 and Period 2. Sulfur (S) is in Group 16 and Period 3. Tin (Sn) is in Group 14 and Period 5.

Step3: Compare with Si

Aluminum is to the left of Si in the same period, so it has a larger atomic radius. Carbon is above Si in the same group, so it has a smaller atomic radius. Sulfur is to the right of Si in the same period, so it has a smaller atomic radius. Tin is below Si in the same group, so it has a larger atomic radius.

Answer:

A. aluminum (Al), D. tin (Sn)
