Question

1. Why are metals used for making electrical cables?
2.
How do non-metals react with water?​

Answer 1

Answer:

metals are good conductor of electricity

Explanation:

almost all metals

even mercury conducts electricity. this is because metals have a valency of 1, 2 or 3 which means they have 1 electrons in their outermost shell.

so the electrons can drift. producing drift velocity and heat.

Reaction of non-metals with water: 

They do not react with water (steam) to evolve hydrogen gas.

Answer 2

Answer:

metals are good conductor of electricity and ductile i.e. can be drawn into thin wire hence they are used for making wires
