Diamond and Graphite.

1. In question one I have to piss a table (the one below) and give the differences between infield and GRAPHITE.

Diamond         black lead

MOLECULE STRUCTURE         

Carbon atoms form a single perplex to 4 other atoms. They argon arranged in tetrahedral geometry. They ar influence in cubes.         Each carbon atom is bonded with three neighbours. They are shaped hexagonal.

PHYSICAL APPERANCE         

Diamond is the hardest thing on earth. It is transparent and very brilliant.         Graphite is a very soft carbon. It is opaque and met totallyic and to unadulterated looking.

PHYSICAL PROPERTIES         

Diamond is an insulator. No mineral can cabbage a infield but a diamond can dinero all other minerals. It has a hardness of 10MOHS. Has a full(prenominal) melting point.         Graphite is a conductor of electricity. All minerals can scratch graphite but it is difficult for a graphite to scratch many minerals, as it is very soft. It has a hardness of 1-2MOHS. Has high melting point.

FUNCTION         

Diamond has captured human interest because it can reflect the fairylike back that has entered it. It can also change while heat into many contrasting colours of the rainbow.         Graphite is used in pencils, high temperature crucibles, dry cells, light arch electrodes boats, trays, jigs moulds, dies and many more(prenominal) uses. White graphite has many technological uses.

        What do the pastime words mean?

a.         Allotrope:

Some elements exist in different forms in the same shape. Like diamond and graphite are twain forms of carbon but their carbons are arranged in different manners.

b. Covalent:

A chemical bond in which two atoms are held together by sharing electrons between them. In graphite each carbon atom forms a strong bond with only 3 carbon atoms.

c. Electric conductivity:

Electric Conductivity is if a material can conduct electricity or not. Like...
