Which property contributes to the non-systematic trend in the melting and boiling points of certain metals compared to alkali metals?

Options

  1. AAtomic mass
  2. BAtomic size
  3. CIonization energy
  4. DElectronegativity

Correct answer

B. Atomic size

Step-by-step solution

The non-systematic trend in the melting and boiling points of certain metals compared to alkali metals is primarily due to differences in atomic size. Smaller-sized atoms tend to have higher melting and boiling points due to stronger metallic bonding.
