Question
Explain why do the group 1 and group 2 elements form diamagnetic and colourless compounds.
✓
Answer
- Unipositive ions of all the elements of group 1 have inert gas configuration and hence, they have no unpaired electron.
- Similarly, group 2 elements can lose their two valence shell electrons and form divalent ions that have inert gas configuration with no unpaired electrons.
