- B. Monatomic
- C. Polymeric
- D. Ionic
5. A student notices that argon does not react even when heated with reactive metals, while sodium reacts vigorously with almost everything. Using ideas about electron arrangement, which explanation is correct?
- A. Argon has more protons than sodium, making it less reactive
- B. Argon already has a full, stable outer shell, so it has no tendency to gain, lose or share electrons, unlike sodium which has one easily lost outer electron
- C. Argon is a gas and sodium is a solid, which alone explains the reactivity difference
- D. Sodium's atoms are smaller than argon's, making sodium more reactive
