Correct Answer:
B. No Chemical Bonding
The correct answer is No Chemical Bonding. Noble gases (Helium, Neon, Argon, Krypton, Xenon, Radon) have their outer electron shells completely filled (full valence shell). This makes them extremely stable and chemically inert under normal conditions. As a result, they exist as monatomic gases, meaning there is no chemical bonding between their atoms. Among the options:
- Ionic Bonding: Requires transfer of electrons, not seen in noble gases.
- No Chemical Bonding: Correct; noble gases have no bonding between atoms.
- Metallic Bonding: Occurs in metals, not in noble gases.
- Covalent Bonding: Requires sharing of electrons, which noble gases rarely do.
Therefore, the correct answer is "No Chemical Bonding".
