What element forms both graphite and diamond?
The element is carbon, and the difference between these two allotropes is the crystal lattice formation that develops in each, based on where each is formed.
What elements are found in benzene?
Carbon and hydrogen. Benzene is a hexagonal ring formed of carbon-carbon bonds, alternatively double and single. http://i205.photobucket.com/albums/bb157/hortaux/benzene.jpg
What substance is pure carbon?
Pure carbon is one kind of element, which is one kind of pure substance.There are several materials that are formed from pure carbon, including:graphiteDiamond. Diamond is elemental carbon that has been exposed to high pressure and temperature for prolonged periods to form the crystal diamond carbon nanotubes(See the links below for other allotropes of carbon)Anthracite coal is nearly pure carbon.
What type of molecules are formed when atoms of different elements combine?
A combination of two atoms of different elements results in a molecule. A combination of two atoms of the same exact element results in two atoms of the same element stuck together, not a molecule. There is no name for this that I know of. --------- 1. Two oxygen atoms: a molecule of oxygen - O2. Many gases has diatomic molecules. Ozone has three oxygen atoms in molecule. 2. Allotropes can be formed from many atoms: allotropes of carbon, sulfur, phosphorus.
What substance is formed when formed when lead oxide is mixed with carbon?
lead oxide + carbon-> lead + carbon dioxide
Do diamonds contain calcium carbonate?
NO!!!! Diamonds are an ALLOTROPE of CARBON. Other allotropes of carbon are graphite and Buckminster Fullerene(Footballene)
What kind of nonmetal is in diamonds?
Carbon, one of the most common solid substances in the universe.
What element forms both graphite and diamond?
The element is carbon, and the difference between these two allotropes is the crystal lattice formation that develops in each, based on where each is formed.
What phases does coal go through before it forms a diamond?
A diamond is not formed from coal. Diamond and coal are both allotropes of carbon, and are formed by different processes.
Which of the following is an example of a carbon allotrope?
There are many allotropes of carbon, some are:Amorphous Carbon (No real structure to speak of)Diamond (Tetrahedral Crystalline Structure)Graphite (Hexagonal 'Graphene' Sheets)C-nanotubes (Cylindrical Graphene)Buckyballs (Spherical Graphene)Note that buckyballs and carbon nanotubes are templates of the 'fullerene family' of carbon allotropes, of which there are many.Another note: Soot is not an allotrope of carbon, it is a collection of particles left from the incomplete combustion of hydrocarbons. Carbon dioxide (CO2) is not an allotrope since it contains oxygen.
Are organic compounds diverse because carbon has many allotropes?
No, organic compounds are diverse because carbon can form up to four covalent bonds with virtually any other nonmetal and can easily form double and triple bonds.aslo, the bonds formed by carbon are very stable, allowing carbon to form long, chain-like molecules. This same versatility in bonding is also the reason carbon as many allotropes.
What elements are found in benzene?
Carbon and hydrogen. Benzene is a hexagonal ring formed of carbon-carbon bonds, alternatively double and single. http://i205.photobucket.com/albums/bb157/hortaux/benzene.jpg
What are 3 different shapes of carbon based molecules?
Carbon occurs in various elemental forms in nature, each with different physical properties.Graphite- Each carbon atom is bonded to three other carbon atoms in the same plane giving long a hexagonal array. One of these bonds is a double-bond, and thus two single and one double bonds satisfy the valency of carbon. Graphite structure is formed by the hexagonal arrays placed one over the other in layers and held together by van der Waals force.Diamond- Each carbon atom is bonded to four other carbon atoms forming a rigid three-dimensional structure.Buckminsterfullerene- Its molecular formula is C-60 and it is in the shape of a football.
Are diamonds only made from coal?
Diamonds are formed from carbon, which is also the base mineral of coal: written another way, both are allotropes -- elementary substances -- of carbon. The difference is in the arrangement of the carbon atoms, with diamonds being examples of an extremely rigid lattice.
What experiment would show that both diamond and graphite are allotropes of carbon?
the diamond (the hardest mineral known to man) is made up of a tetrohydral shaped atom structure which is formed into a complex lattice arrangement in the element. Graphite by contrast is one of the weakest minerals known to man, because its atoms are bonded by very weak bonds in fragile layers/sheets above and below one another, but each layer is not bonded to the rest.The carbon-carbon bonds in both minerals are actually quite strong, but it is the application of those bonds that make the difference.The carbon atoms are arranged differently in diamonds and graphite. They are both carbon, but their internal structure is different. They are allotropes of carbon.
What substance is pure carbon?

How are types of carbon formed?
Allotropes of carbon, that is the different structures pure carbon forms are made in the following ways. graphite is formed by carbon deposits put under pressure causing the carbon to form hexagonal latticed sheets. When graphite is subject to intense pressure and heat it will form a much stronger crystal lattice which is diamond. Graphene Graphene is difficult to make, it is essentially a single sheet of graphite just one molecule thick. it is normally chemically synthesized at a great cost. You can make it in you own home however by rubbing some graphite pencil lead on sellotape folding it over then tearing it back. And there's a small chance that you may peel off a layer 1 molecule thick. Not that you'd notice.
