Question

metals are good conductors of heat and electricity . give reason​

Answer 1

Answer:

-this is because metals like copper, iron etc. have a high concentration of free electrons that helps in the conduction of electricity.

- more free electrons results in better conductivity.

- whereas on the other hand non conductors either have a very negligible amount of free electrons or no free electrons at all.

hope it helps :)

Answer 2

Answer:

No it is wrong

for electricity alluminium or copper are used for the electricity.
