Question
- How does basic character of oxides and hydroxides down the group in alkali metals change? Why?
- How does reducing power of elements vary in Group I?
✓
Answer
- It goes on increasing down the group due to decrease in ionisation energy and increase in metallic character.
- Reducing power of 'Li' is highest, Na is lowest, then it goes on increasing:
Li > Cs > Rb > K > Na.
