Question

Give mean the all questions answer please

Answer 1

1. In addition, the ionization energy of the atom is too large and the electron affinity of the atom is too small for ionic bonding to occur. For example: carbon does not form ionic bonds because it has 4 valence electrons, half of an octet. To form ionic bonds, Carbon molecules must either gain or lose 4 electrons.
2. In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. ... Catenation occurs most readily with carbon, which forms covalent bonds with other carbon atoms to form longer chains and structures. This is the reason for the presence of the vast number of organic compounds in nature.
3. Carbon Forms Covalent Bonds. The most common type of bond formed by carbon is a covalent bond. In most cases, carbon shares electrons with other atoms (usual valence of 4).
4. Other than the three main allotropes of graphite, diamond, and buckminsterfullerene, scientists continue to discover new allotropes for this amazing atom. For example, engineers and scientists are especially curious about graphene, which is made from one single sheet of the carbon atoms that make up graphite.
5. Geologists believe that the diamonds in all of Earth's commercial diamond deposits were formed in the mantle and delivered to the surface by deep-source volcanic eruptions. ... The formation of natural diamonds requires very high temperatures and pressures.
6. Sources of Diamonds in the United States. Diamonds are found in three states: Arkansas, Colorado and Wyoming. They occur at the Colorado-Wyoming state line area which was named the Aultman, Ferris and Schaffer Kimberlites.
7. Diamond has a giant molecular structure. Each carbon atom is covalently bonded to four other carbon atoms. A lot of energy is needed to separate the atoms in diamond. This is because covalent bonds are strong, and diamond contains very many covalent bonds.
8. they are ideal for grinding, cutting, drilling, and polishing. When used as an abrasive, very small pieces of diamond are embedded into grinding wheels, saw blades, or drill bits.
