Question: Why are graphite and diamonds different?

Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. … Graphite is very soft and has a hardness of 1 to 2 on this scale. Diamonds are the hardest known natural substance and have a hardness of 10.

Why diamond and graphite are different from each other?

Graphite also has a lower density (2.266 grams per cubic centimeter) than diamond. The planar structure of graphite allows electrons to move easily within the planes. This permits graphite to conduct electricity and heat as well as absorb light and, unlike diamond, appear black in color.

What is the difference between diamond and graphite?

Diamond and graphite are allotropes of carbon. These have different chemical and physical properties. The main difference between diamond and graphite is that diamond is made out of sp3 hybridized carbon atoms whereas graphite is made out of sp2 hybridized carbon atoms.

What are 3 differences between diamond and graphite?

How are graphite and diamond similar and different?

Both graphite and diamonds are made out of pure carbon. The chemical composition of the two is exactly the same. This makes graphite and diamonds allotropes of carbon along with amorphous, which is commonly called soot or carbon black. … The difference lies in how all the carbon atoms align and connect to one another.

What causes the difference in hardness between graphite and diamond?

In diamond, the carbon atoms have solid bonds in three measurements, makings it hard. In graphite the bonds create in level layers with carbon atoms having solid bonds on the very same layer with weaker layers above as well as below that makes this graphite weak.

Why do diamond and graphite differ in physical properties?

It’s because the carbon atoms are rearranged in a specific geometric shape that gives the diamond its properties. … Graphite however, is when the carbon atoms bond together in sheets – hexagonal-like lattice. Graphite is formed from the carbon atoms resulting from the metamorphism of minerals such as marble, quartz, etc.

What are the main two difference between graphite and diamond?

Explain the difference in properties of diamond and graphite on the basis of their structures.

DIAMOND GRAPHITE
1) It has a crystalline structure. 1) It has a layered structure.
2) It is made up of tetrahedral units. 2) It has a planar geometry.
