Chemical formula of diamond

2019-4-28 · This is why graphite can conduct an electric current. Graphite unlike diamond is extremely soft. Between the parallel layers of graphite are weak intermolecular bonds, which allow the layers to easily slip over each other. This is what happens when writing or drawing with a graphite pencil on paper.

Does graphene conduct electric power? - Quora

Graphene does conduct electricity. This is because of its structure. In graphene, each carbon atom is covalently bonded to 3 others. There is always a fourth atom free atom. This atom contains free ‘delocalised’ electrons that can carry and pass o

Silicon - Element information, properties and uses

Silicon is also used to make silicones. These are silicon-oxygen polymers with methyl groups attached. Silicone oil is a lubricant and is added to some cosmetics and hair conditioners. Silicone rubber is used as a waterproof sealant in bathrooms and around windows, pipes and roofs.

GIANT COVALENT STRUCTURES - chemguide

2019-1-28 · Note: The logic of this is that a piece of graphite ought only to conduct electricity in 2-dimensions because electrons can only move around in the sheets - and not from one sheet to its neighbours. In practice, a real piece of graphite isn''t a perfect crystal, but a host of small crystals stuck together at all sorts of angles.

How do solar cells work? - Explain that Stuff

Semiconductors like silicon are neither conductors nor insulators: they don''t normally conduct electricity, but under certain circumstances we can make them do so. A solar cell is a sandwich of two different layers of silicon that have been specially treated or doped so they will let electricity flow through them in a particular way. The lower
