Which of the following is NOT true for alkaline earth metals?

Options

  1. ATheir divalent ions have inert gas configuration
  2. BThey are more electropositive than alkali metals
  3. CAlkaline earth metals are silvery white and soft
  4. DTheir compounds are diamagnetic and colourless

Correct answer

B. They are more electropositive than alkali metals

Step-by-step solution

- Alkali metals have low ionization energies and their atoms readily lose the valence electron hence they are most electropositive elements. - Compound of alkaline earth metals are diamagnetic and colour less.
