what are its surface properties?
Diamonds are naturally lipophilic and hydrophobic, which means the diamonds' surface cannot be wet by water, but can be easily wet and stuck by oil.

describe carbon in covalent bonds and the importance of it It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds what are the characteristics of this element? Carbon is the sixth element, with a ground-state electron configuration of 1s2s2p, of which the four outer electrons are valence electrons. Its first four ionisation energies, 1086.5, 2352.6, 4620.5 and 6222.7 kJ/mol, are much higher than those of the heavier group-14 elements. where this element can be found in the earth? Earth's crust what are its most common allotropes? Amorphous carbon, graphite, and diamond how did this element get its name? The English name "carbon" comes from the Latin "carbo" for coal and charcoal, whence also comes the French "charbon", meaning charcoal. what is the last allotrope? Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. what can you tell about its electrical conductivity properties? Blue diamonds are natural semiconductors, in contrast to most diamonds, which are excellent electrical insulators.

Diamond [SEP] Surface property
Diamonds are naturally lipophilic and hydrophobic, which means the diamonds' surface cannot be wet by water, but can be easily wet and stuck by oil. This property can be utilized to extract diamonds using oil when making synthetic diamonds. However, when diamond surfaces are chemically modified with certain ions, they are expected to become so hydrophilic that they can stabilize multiple layers of water ice at human body temperature. The surface of diamonds is partially oxidized. The oxidized surface can be reduced by heat treatment under hydrogen flow. That is to say, this heat treatment partially removes oxygen-containing functional groups.
