Which of the following is NOT true for alkaline earth metals?
Options
- ATheir divalent ions have inert gas configuration
- BThey are more electropositive than alkali metals
- CAlkaline earth metals are silvery white and soft
- 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.
