are all metals conductors?

Answer 1

A conductor is defined as a material with high conductivity, although this judgement is somewhat subjective. Metals are good conductors because metals are, by definition, held together by metallic bonds, in which electrons are free to move throughout the structure. Thus, metals are always good conductors compared to non-metals. Some metals are much better conductors than others.

Answer 3

No.Not all metals are conductors at normal roon temperature.
But most of them are due to the availability of free electrons in their valance shell.
Na,Al,Fe are good conductors where as Ag Au are the best conductors.Mercury(Hg) does not conduct elecrticity at room temperature but when it is a super conductor its resistance becomes~0.

Answer 4

OK Sarah, how do you define a metals first. Metals are chemicalls peaking, defined in the Periodic table of elements from a certain number to a certain number. As far as I understand it, most elements are metals in one form or another. But not all metals are conducting. Silicon and its allied elements are called not metals, but again many do it. and they are not conducting that much.

All common metals such as Gold, copper and Iron are conducting at different degrees. The degrees are defined by conductivity scales - so Copper is always more conducting than iron.

Answer 5

conductor r those which can conduct electricity basically electrons

only materials with valence(free) electrons can conduct electricity effectively and metals have free e- in abundance and also they don't have energy gap b/w valence band and transition band hence all metals r good conductors
