Diamond has a giant covalent structure in which: each carbon atom is joined to four other carbon atoms by covalent bonds. the carbon atoms have a regular lattice arrangement.
Is a diamond a compound element or mixture?
It’s a heterogeneous mixture. Diamond is made of just one element: carbon. Each carbon atom in diamond is connected to four other carbon atoms, in a crystal that extends on and on. There are other forms of pure carbon where the atoms are bonded differently, notably charcoal and graphite.
Is Diamond a molecular compound?
4 Answers. Diamond is a covalent network solid, like a number of other common materials (quartz, graphite, glass, and a whole bunch of stuff). Because they are not discrete molecules – there is no ‘diamond’ molecule the same way there are molecules of caffeine, benzoic acid, citric acid, N,N-dimethylaminopyridine, etc.
Is a diamond a substance?
Diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.
Are diamond and graphite element?
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.

Why is diamond not an element?
A diamond is composed of Carbon, which is an element. When Carbon clumps together in a patternless shaped form, and then pressure is applied, a diamond is formed. This makes the diamond made of really only carbon, so it is not an element on its own, and it is not a compound, having made by only 1 type of thing.
Is tea a compound element or mixture?
A Tea is a solution of compounds in water, so it is not chemically pure. It is usually separated from tea leaves by filtration. B Because the composition of the solution is uniform throughout, it is a homogeneous mixture.
What is Diamond chemically?
Diamond is a form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it.
What is the symbol of diamond?
The element in diamond is carbon so chemical symbol of diamond is C. Diamonds, particularly high quality ones, are very pure carbon.
Can a diamond conduct electricity?
Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. … It does not conduct electricity as there are no delocalised electrons in the structure.
What is a diamond shape called?
The rhombus is often called a diamond, after the diamonds suit in playing cards which resembles the projection of an octahedral diamond, or a lozenge, though the former sometimes refers specifically to a rhombus with a 60° angle (which some authors call a calisson after the French sweet – also see Polyiamond), and the …
Is Diamond an ore?
There is no mineral ore of diamond. An ore is a rock which is crushed, refined, treated & something is retrieved from it by physical or chemical processes. Diamonds are found within kimberlite, & in Australia in lamproite, but diamond is a crystal of carbon & is not part of the rock, so the rock is not an ore.
What made diamond a mineral?
Diamonds are made entirely of carbon so they easily fall into this category. A mineral has an ordered internal structure. The elements that make up a mineral are always in a fixed systematic and repeating structure. This helps to cause the rigid solid structure of minerals, diamonds included.
Which is harder graphite or diamond?
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.
What are the similarities and differences between graphite and diamond?
Diamond has a tetrahedral structure and is the hardest material known to man. There are strong covalent bonds between carbon atoms and each carbon atom is bonded to 4 other carbon atoms. Graphite has a hexagonal layered structure and each carbon is bonded via strong covalent bonds to 3 other carbon atoms.
What is the difference between the structure of diamond and graphite?
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.
