What makes a diamond and graphite two froms of the element carbon so different?
They are so different because of the way the carbon atoms bond to each other. Graphite has layers of very strong bonds, but the layers are very weakly bonded to each other. Diamonds are so strong because all of its carbon atoms are uniformly bonded to one another.
Diamonds and pencil "lead" are made entirely of the element carbon (C, atomic # 6). Graphite is the correct term for pencil "lead," which obviously isn't really lead. Diamond and graphite are allotropes, which means different atomic arrangements of the same element. Diamond and pencil lead (graphite) are both forms of the element carbon. Different pure forms of an element, like diamond and graphite, are called allotropes. In diamond the carbon atoms are arranged in…
We know that graphite is a natural mineral and it is an allotrope of the element carbon. It's similar to diamond, which is a natural mineral that is also an allotrope of the element carbon. It may not be correct to say that graphite is a native element, but it is really a naturally occurring mineral that is composed of the element carbon.
Diamond and graphite are polymorphic - minerals with the same chemical formula but of different crystal structure. Both are made only of the element carbon. Because they form under different conditions of temperature and pressure, their crystal structure arranged differently. Hence, the vastly different physical properties. Diamonds and graphite are separate allotropes of carbon, different because of their atomic structures. Carbon formed as diamond is the hardest mineral on earth.
Graphite is just an allotrope of the element carbon, in that it is carbon in a different form. Graphite exists in a hexagonal planar structure which allows sheets of graphite to slide over each other easily which is what you see when you write; it is also used as a lubricant (though not in a vacuum) The allotropes of Carbon include diamond, graphite and fullerenes.
Graphite is a naturally occurring mineral that is composed of the element carbon (C). Graphite is made up of lots and lots of layers of carbon laid one on top of the other, and it is one allotrope of this element. Diamond, another natural mineral, is also made up of carbon. It is likewise an allotrope of that element, just as graphite is.
They have different structures. They are both made up of Carbon (diamond has more Carbon atoms though) but the reason that graphite and diamond are so different in shape, hardness, etc, is due to how it is structured. The carbon atoms themselves are identical, the inter-atom bonding is different. Graphite - carbon atoms bond in flat hexagons that tessellate flat sheets. Diamond - carbon atoms bond in cubes that form a cubic crystal solid.
