Answer 2

a. Carbon:

Complete electron configuration notation: 1s^2 2s^2 2p^2

Noble gas notation: [He] 2s^2 2p^2

Orbital notation: ↑↓ 1s ↑↓ 2s ↑↓ 2p

b. Neon:

Complete electron configuration notation: 1s^2 2s^2 2p^6

Noble gas notation: [He] 2s^2 2p^6

Orbital notation: ↑↓ 1s ↑↓ 2s ↑↓ 2p

c. Sulfur:

Complete electron configuration notation: 1s^2 2s^2 2p^6 3s^2 3p^4

Noble gas notation: [Ne] 3s^2 3p^4

Orbital notation: ↑↓ 1s ↑↓ 2s ↑↓ 2p ↑↓ 3s ↑↓ 3p
