Explanation:

Elements in the same group (vertical column) of the periodic table have identical valence electron configurations, leading to similar bonding, physical, and chemical properties. For each question, match the given element to its group member:

1. Carbon is in Group 14; silicon is also in Group 14.
2. Magnesium is in Group 2; strontium is also in Group 2.
3. Neon and krypton are noble gases (Group 18); helium is a noble gas with lower atomic mass than both.
4. Sodium is in Group 1; lithium is also in Group 1.
5. Chlorine is in Group 17; iodine is also in Group 17.
6. Krypton is in Group 18; helium is also in Group 18.
7. Nitrogen is in Group 15; phosphorus is also in Group 15.
8. Lead is in Group 14; tin is also in Group 14.

Answer:

1. B silicon
2. C strontium
3. H helium
4. B lithium
5. D iodine
6. C helium
7. B phosphorous
8. D tin
