Why are graphite and diamond not similar?
Graphite and Diamond are different because they have different structures. Both have Giant Covalent Structures, resulting in very high melting temperatures. However each carbon atom in Diamond has 4 covalent bonds with other Carbons, making it extremely strong and hard.
How is diamond and graphite similar?
Diamond and graphite are both allotropes of carbon. This means they are both made up of carbon atoms arranged differently and exist in the same physical state. They both have a giant covalent structure. Diamond has a tetrahedral structure and is the hardest material known to man.
Why do diamonds and graphite look so different?
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. Answer originally posted May 20, 2002.
What is diamond and graphite?
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.
How does diamond and graphite differ in terms of electrical conductivity and hardness?
Graphite, for example, has a melting point of more than 3,600°C. Variable electrical conductivity – diamond does not conduct electricity, whereas graphite contains free electrons so it does conduct electricity. Silicon is a semi-conductor – it is midway between non-conductive and conductive.
Are diamond and graphite allotropes?
Diamond, graphite and fullerenes (substances that include nanotubes and ‘buckyballs’ , such as buckminsterfullerene) are three allotropes of pure carbon.
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.
What are diamonds made of?
Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals.
