And 3- Metals on lower end of activity scrues. will be more recyclable than those on upper end. The metals on upper and are highly reactive and have strong tendency to get onidized. So recycling them is not easy. But the metals at coluer and are not much reactive like gold, etc. They are easily recyclable as do not onidize in contact of air. They are noble compared to metals up in series. - Ans. 4 when landfills will be used to dispose mater soluble materials, following are the concerns : i It will enter water table and will pollute . the underground water - i) it will destruct the quality of soil and the organisms will be exposed to these mater soluble materials through water. I ni) Plants will alson effected when these water soluble materials through water will be exposed to its roots. iw) when the water will be consumed by es Scanfumans which have these materials, Camshawill cause severe health issues.
