the bonding in an inert gas crystal is due to
Correct answer: D. van der waals binding
- A. metallic bonding
- B. covalent bonding
- C. ionic bonding
- D. van der waals binding
Explanation
Inert gases, also known as noble gases, are elements in Group 18 of the periodic table. They have completely filled outer electron shells, making them very stable and unreactive. As a result, they do not form chemical bonds with other atoms, either covalent or ionic.However, inert gas atoms can form weak intermolecular attractive forces known as van der Waals forces. These forces arise from temporary fluctuations in electron density, creating short-lived, weak dipoles that interact with neighbouring atoms. Van der Waals forces are responsible for the bonding in inert gas solids, leading to the formation of weak, non-polar crystals with low melting and boiling points

About Ionic and Molecular Crystals
Ionic crystals contain oppositely charged ions held by electrostatic forces, whereas molecular crystals contain discrete molecules joined by weaker intermolecular forces. Their structures explain differences in melting point, hardness, volatility, solubility and electrical conductivity, especially between solid and molten states.
