Carbon alone forms the familiar substances graphite and diamond. Both graphite and diamond are made only of carbon atoms. Graphite is very soft and slippery. Diamond is the hardest substance known to man. If both are made only of carbon what gives them different properties? The answer lies in...

Why is it good that humans cannot digest cellulose? Why is graphite soft and slippery? Why do exoskeletons shed? Why does electrocuting a nerve stimulate a response? Why is graphene used in pencils? Why does the crust float on the mantle?
The structure of diamond is very rigid. Each carbon atom in it is joined to four other carbon atoms forming a rigid tetrahedron structure. One carbon atom is present at the centre of a regular 1 tetrahedron while four others occupy the corners. This type
