- name a non metal with valency 3
- Give reason Alkali metals are good reducing agents

- Explain why are the following statements not correct : (1)All groups contain metals and non-metals. (2)Atoms of elements in the same group have the same number of electron(s). (3)Non-metallic character decreases across a period with increase in atomic number. (4)Reactivity increases with atomic number in a group as well as in a period.
