Question

Name the mineral which has covalent bond?

Answer 1

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. The covalent bond is the strongest of all chemical bond types.

Complete answer:
Covalent bonds are very strong bonds formed when atoms share electrons with neighboring atoms. Sulfur, and both of carbon's natural forms, graphite and diamond, are covalently-bonded minerals.
Examples of compounds that contain only covalent bonds are methane, carbon monoxide, and iodine monobromide. Covalent bonding between hydrogen atoms: Since each hydrogen atom has one electron, they are able to fill their outermost shells by sharing a pair of electrons through a covalent bond. Each carbon atom in the diamond crystal lattice is covalently bonded to sharing its valence electrons with four neighboring carbon atoms. A diamond crystal is held together by nothing but extremely strong covalent bonds in all directions, which makes diamond a very hard mineral, the hardest known.

Note:
Most minerals are characterized by ionic bonds, covalent bonds, or a combination of the two, but there are other types of bonds that are important in minerals, including metallic bonds and weaker electrostatic forces. Other minerals characterized by ionic bonding include fluorite, calcite and many others. Covalent bonding is another very strong type of chemical bond.
