Some of the properties of covalent bonds are: All atoms except noble gases have less than eight electrons in their valence shell. Covalent compounds also are known as molecular compounds. Often, the nonmetal is carbon, but other examples of elements include phosphorus, oxygen, nitrogen, hydrogen, and halogens like chlorine. In Lewis terms a covalent bond is a shared electron pair. For example, the word covalent bond has the following synonyms: . Covalent bonds usually happen between two atoms which are fairly close in electronegativity, and which are nonmetal in nature. The more electronegative atom is said to have a partial negative charge and the less electronegative atom has a partial positive charge in the polar covalent bond. (65) What can I say instead of "covalent bond"? The electrovalent bond weakens and the covalent bond strengthen between manganese and oxygen due to ion polarization effect, which makes the spinel structure more stable.
