Is a metal or non metal a nonconductor?

Answer 1

Almost everything is a good conductor of sound, but a conductor of heat and electricity are usually only metals. A nonmetal can be an insulator, or something that doesn't conduct things, for heat and electricity.

Answer 2

If a substance have free electrons or ions, then it can act as a conductor of electricity. Metals have free electrons and hence generally act as good conductors of electricity.

Answer 3

Most metals are conductors. Some don't conduct all that well, but nearly all of them conduct better than most nonmetals.

Answer 4

Conductors are usually metals, except non metals, such as, graphite, which are good conductors of electricity.

Answer 5

All metals are conductive, and some non- metals are conductive such as Carbon.

Answer 6

if an item conducts electricity it is a Metal

Graphite, a form of carbon which makes up the leads in pencils is the only non-metal that conducts electricity

Answer 7

Many materials are nonconductors: porcelain, coal, concrete, bricks etc.
