Which of the following is NOT true for alkaline earth metals?
Which of the following is NOT true for alkaline earth metals?
Their divalent ions have inert gas configuration
They are more electropositive than alkali metals
Alkaline earth metals are silvery white and soft
Their compounds are diamagnetic and colourless
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.
