Which one is harder a diamond or a graphite explain your answer?

Diamond is harder than graphite because each of its carbon atoms form four covalent bonds in a tetrahedral structure and also due to the presence of strong covalent bonds in it. A chemical bond involving the exchange of electron pairs between atoms is known as a covalent bond.

What is harder diamond or graphite?

We know that both diamond and graphite are made of carbon. However, diamond is harder than graphite because of the carbon atoms in a diamond form 4 covalent bonds in the form of tetrahedral structure. … This is the reason why diamond is harder than graphite.

Why is diamond harder than graphite GCSE?

In diamond, each carbon atom forms 4 covalent bonds in a tetrahedral structure. Whereas, in graphite the carbon atoms only form 3 covalent bonds, creating hexagonally packed sheets of carbon. The sheets of carbon become bonded by weaker intermolecular forces.

Why is diamond harder than graphite quizlet?

Why? layers of carbon atoms that can slide over each other easily. In Diamond each carbon atom is strongly (covalently) bonded to 4 others. . Graphite can conduct electricity but diamond cannot.

Why diamond is hardest and graphite is softest?

Graphite is soft because it has weak inter molecular forces between its layers. Diamond is hard due to its giant covalent lattice and it has many strong covalent bonds.

Why is a diamond hard?

Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals. … That’s why a diamond is such a hard material because you have each carbon atom participating in four of these very strong covalent bonds that form between carbon atoms.

Which is harder diamond or graphene?

Graphene, on the other hand, is the strongest material ever recorded, more than three hundred times stronger than A36 structural steel, at 130 gigapascals, and more than forty times stronger than diamond.

Why do diamond is very hard as compared to the graphite although both are allotropes of carbon explain?

While there are strong covalent bonds between carbon atoms in each layer, there are only weak forces between layers. This allows layers of carbon to slide over each other in graphite. … In this rigid network atoms cannot move. This explains why diamonds are so hard and have such a high melting point.

Why is diamond hard GCSE?

The rigid network of carbon atoms, held together by strong covalent bonds, makes diamond very hard. … Like silica, diamond has a very high melting point and it does not conduct electricity.

Why is graphite different from diamond?

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.

What are the main factors that account for the extreme hardness of diamond?

The heat and pressure causes the diamonds molecules to change so that they’re so close together, the molecules can’t move (known as covalent bonding). The closeness of these molecules forms a rigid bond, therefore making the diamond hard.

How strong is graphite?

Graphite is known to be one of the weaker allotropes of carbon. It is not known to possess high tensile strength and is known to easily crumble under force. Pencil leads are often made up of graphite.

Is graphite strong or weak?

The forces between the layers in graphite are weak. This means that the layers can slide over each other. This makes graphite slippery, so it is useful as a lubricant . Explain why diamond does not conduct electricity and why graphite does conduct electricity.

Why is graphite softer than diamond 4 marks?

Graphite. Graphite is a form of carbon in which the carbon atoms form covalent bonds with three other carbon atoms. … These layers can slide over each other, so graphite is much softer than diamond.
