why are metals good electricty conductors?

Metals are good conductors of electricity because the delocalised electrons in the metal carry electrical charge through the metal.

why are metals good conductors of thermal energu?

Metals are good conductors of thermal energy because energy is transferred by the delocalised electrons

in diamond each carbon atom forms covalent bonds with other carbon atoms in a ____ ____ ____ so diamond is very ____ and has a very ___ mp and _____ conduct electricity

In diamond, each carbon atom forms four covalent bonds with other carbon atoms in a giant covalent structure, so diamond is very hard, has a very high melting point and dont conduct electricity.

in graphite each carbon atom forms ___ covalent bonds with ___ other carbon atoms forming layers of ______ ___ which have covalent bonds between __ _____ in graphite _ electron from each carbon atom is _

In graphite, each carbon atom forms three covalent bonds with three other carbon atoms, forming layers of hexagonal rings which have no covalent bonds between the layers. In graphite, one electron from each carbon atom is delocalised.

how is graphit esimilar to metals?

graphite is similar to metals in that it has delocalised electron

graphene is a ___ layer of ___ its properties make it useful in ____ and ___

Graphene is a single layer of graphite its properties make it useful in electronics and composites.

fullerenes are ____ of carbon atoms with ____ shapes. the structure of fullerenes is based on ______ rings of carbon atoms but also contain rings with ___ or ___ carbon atoms. the first fullerene discovered was ___________ which has a _____ shape

Fullerenes are molecules of carbon atoms with hollow shapes. The structure of fullerenes is based on hexagonal rings of carbon atoms but they may also contain rings with five or seven carbon atoms. The first fullerene to be discovered was Buckminsterfullerene (C60) which has a spherical shape.

Carbon _______ are ______ fullerenes with ____ ___ _____ to diameter ___. Their ______ make them ____ for nanotechnology, electronics and ______.

Carbon nanotubes are cylindrical fullerenes with very high length to diameter ratios. Their properties make them useful for nanotechnology, electronics and materials.
