Question

answer the following questions
1. which is the most active metal ?why
2.what would be observed if B is added to a copper sulphate solution and why
3. Arrange the metals A,B,C,D in order of increasing reactivity
4. Container of which metal can be used to store both zinc sulphate solution and silver nitrate solution ?
5. which of the above solution can be stored in a container made up of these metals

Answer 1

1-cesium is the most active metal even francium is more reactive but its as radioactive so we consider cesium
as we know that by going down the group reactivity increases because distance from nucleus to outermost shell increases so force of attraction decreases and it donates the electron easily.
