Questions and Answers

Why does the boiling point of elements tend to increase when moving from left to right across a period until reaching around the middle of the table?

  • The strength of metallic bonds decreases from left to right.
  • The intermolecular forces of nonmetals increase.
  • The metallic character decreases from left to right.
  • The strength of metallic bonds increases from left to right. (correct)
  • Which elements are more likely to have higher boiling points, metals or nonmetals?

  • Both metals and nonmetals
  • Neither, as boiling points are not influenced by the type of element
  • Metals (correct)
  • Nonmetals
  • Why do nonmetals generally have lower boiling points than metals?

  • Nonmetals have stronger metallic bonds.
  • Nonmetals are positively charged.
  • Nonmetals have weaker intermolecular forces than metallic bonds. (correct)
  • Nonmetals are denser than metals.
  • What is the primary reason for the change in boiling point when moving across a period from metals to nonmetals?
