I have 2 chemistry books and they say 2 different things.

which is it?

Diamond is a good conductor of heat because the electrons in the bonds are shared, so the heat can spread out easily.

I don't think it is.

:ditto:
basically due to its strong covalent bonds

I think it's a bad conductor - because the electrons are all pretty much fixed in one position, and can't move a great deal to carry the heat. Whereas in a metal, you have lots of free electrons to do it for you.

Water has pretty strong covalent bonds as well, but it's a rubbish conductor of heat.

Nope diamond is a poor conduct of heat and electricity as there are no delocalised electrons (mobile charged particles) to transfer current.

More convalency = less conductivity! Dont we have any A level chemists here or something?

indeed it is but its unusual because its a very poor electrical conductor.

What have covalent bonds got to do with carrying heat, exactly?

Its a very very good conductor of heat, hence why if you breath on it the condensation disapears almost immediatly. diamonds dont conduct electricity though.

Because of its strong covelent bonds, vibrations travel easily through the stiff lattice, so its a good thermal conductor.

AARGHHH!!! its a bad electrical conductor due to no delocalised electrons, as they are the ones that carry a charge.
but heat has nothing to do with electrons its to with bonds
I've been doing so many past papers with questions on diamond and have seen what it says in the mark scheme.

thank you! lol

btw is it possible that different exam boards accept different answers
