Explanation
Neon as a Noble Gas Steps:
- Identify neon's position in Group 18, confirming its stable electron configuration.
- Evaluate statement 1: Neon has a full valence shell (8 electrons), making it unreactive—correct.
- Evaluate statement 2: Neon does not readily form compounds due to high ionization energy—incorrect.
- Evaluate statement 3: Neon exists as a monatomic gas at standard conditions—correct.
Why B is correct:
- B selects statements 1 and 3, aligning with neon's noble gas properties per the octet rule.
Why the others are wrong:
- A includes incorrect statement 2.
- C omits correct statement 3.
