Answer

Answer:

Carbon has 2 shells of electrons, and silicon has 3 shells of electrons.

Explanation:

Step1: Analyze atomic mass

Atomic mass of carbon is approximately 12, not 6. Atomic mass of silicon is approximately 28.1, not 14. So the first option is wrong.

Step2: Analyze electron - shell number

Carbon (atomic number (Z = 6)) has electron configuration (1s^{2}2s^{2}2p^{2}), so it has 2 electron shells. Silicon ((Z=14)) has electron configuration (1s^{2}2s^{2}2p^{6}3s^{2}3p^{2}), so it has 3 electron shells.

Step3: Analyze electron number

Carbon ((Z = 6)) has 6 electrons (in a neutral atom, number of electrons = number of protons = atomic number). Silicon ((Z = 14)) has 14 electrons. So the third option is wrong.

Step4: Analyze proton number

Carbon ((Z = 6)) has 6 protons. Silicon ((Z=14)) has 14 protons. So the fourth option is wrong.
