Why diamond and graphite are different minerals although composed of the same chemical element?
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.
Why is diamond and graphite 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 is diamond very hard than graphite even though both are molecular structures?
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. … Therefore, diamond is hard but graphite is soft and slippery even though both have carbon present in them.
How does the chemical bonding of graphite and diamond differ?
Differences 1. Diamond: each carbon atom bonds to 4 other carbon atoms, WHILST, Graphite: each carbon atom bonds to 3 other carbon atoms. Thus, diamond bears more of a tetrahedral structure, whereas graphite takes the form of layers. The presence of layers means that atoms can slide over each other easily.
Why is diamond hard and graphite not note that diamond and graphite are both composed of carbon atoms?
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.
What is the relationship between diamond and graphite?
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.
How are diamonds and graphite the same How are they different quizlet?
Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. As a result, diamond is very hard and has a high melting point. It does not conduct electricity. Graphite is a form of carbon in which the carbon atoms form layers.
Why is graphite less dense than diamond?
Graphite has a lower density than diamond. This is because of the relatively large amount of space that is “wasted” between the sheets. … Attractions between solvent molecules and carbon atoms will never be strong enough to overcome the strong covalent bonds in graphite. conducts electricity.
Why is graphite more reactive than diamond?
Graphite is the most stable allotrope of carbon. … Density: Graphite’s specific gravity is 2.3, which makes it lighter than diamond. Chemical activity: it is slightly more reactive than diamond. This is because the reactants are able to penetrate between the hexagonal layers of carbon atoms in graphite.
Why is diamond stronger 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.
