- BThe intermolecular forces between the atoms become stronger.
- CThe density increases.
- DThe chemical reactivity increases.
- EThe boiling point increases.
Argon could be used as a shielding gas when welding two pieces of metal. Which statement explains why this is the case?
- AArgon has a high dispersion force, so it stops air from getting to the metal.
- BArgon has a low melting point, so it stops air from getting to the metal.
- CArgon is denser than air, so it stops air from getting to the metal.
- DArgon is inflammable, so it stops air from getting to the metal.
- EArgon has a high melting point, so it stops air from getting to the metal.

Comparing radon with krypton, which of the following is correct?
- ARadon is denser because it has a greater ionic force.
- Bkrypton is denser because it has a greater ionic force.
- CKrypton is denser because it has a greater dispersion force.
- DBoth have the same density.
