Question
What happens to the level of softness as we progress down the group of alkali metals?
- Increases
- Decreases
- Stays the same
- Varies randomly
Hint:
Softness increases down the group.
The correct answer is: Increases
- Alkali metals have large atomic size, moving down the group strength of metallic bond decreases.
- The close packing of atom is weak.
- The softness of alkali metals increases down the group with increasing atomic number.
