Question

Use the periodic table to determine which elements are likely to have a larger atomic radius than silicon (Si). Check all that apply.
aluminum (Al)
carbon (C)
sulfur (S)
tin (Sn)

Answer 1

Answer

• aluminum (Al)  
• tin (Sn)

Explanation

1. aluminum (Al)

• Al has large atomic radius than Si because in periodic table atomic radius decreases from left to right, as Al is present 3A group while Si is present in 4A.

2. carbon (C)

• C has small atomic radius than Si because in periodic table, atomic radius increases down the group, as both C and Si are present in same group, C is present at Top while Si at bottom.

3. sulfur (S).

• S has small atomic radius than Si because in periodic table atomic radius decreases from left to right, as S is present 6A group while Si is present in 4A.

4. tin (Sn)

• Tin has large atomic radius than Si because in periodic table, atomic radius increases down the group, as both Tin and Si are present in same group, Si is present at Top while Tin at bottom.
