Covalent Bond Biology Dictionary Definition. a covalent bond or molecular bond is a chemical link between two atoms where electron pairs are shared. covalent bonds form between two non metal atoms and non metal compounds that possess the same or similar values of attraction (electronegativity). electron pairs shared in a covalent bond are known as shared pairs or bonding pairs. In biology, the covalent bond is one of the three major types of chemical bonds that are biologically important; the other two are ionic bonds and hydrogen bonds. the covalent bond, though, is distinct from these two bonds in such a way that the electrons are shared between atoms, ions, or molecular constituents of a biological compound.
Covalent Bond Biology Dictionary A covalent bond is formed when two atoms share one or more pairs of electrons, with the shared electrons usually coming from the outer shells of the atoms involved. each atom contributes one or more electrons to the shared pair, resulting in the formation of a stable compound. this sharing of electrons allows both atoms to achieve a full outer. These bonds much more common than ionic bonds in the molecules of living organisms. covalent bonds are commonly found in carbon based organic molecules, such as our dna and proteins. covalent bonds are also found in inorganic molecules like h 2 o, co 2, and o 2. one, two, or three pairs of electrons may be shared, making single, double, and. These bonds are stronger and much more common than ionic bonds in the molecules of living organisms. covalent bonds are commonly found in carbon based organic molecules, such as our dna and proteins. covalent bonds are also found in inorganic molecules like h 2 o, co 2, and o 2. one, two, or three pairs of electrons may be shared, making single. 5.7: covalent bonds. page id. michael w. klymkowsky and melanie m. cooper. university of colorado boulder and michigan state university. in the case of van der waals interactions, the atoms and molecules involved retain their hold on their electrons, they remain distinct and discrete. there are cases, however, where atoms come to "share" each.

Covalent bonds are commonly found in carbon based organic molecules, such as our dna and proteins. covalent bonds are also found in inorganic molecules like h 2 o, co 2, and o 2. one, two, or three pairs of electrons may be shared, making single, double, and triple bonds, respectively. the more covalent bonds between two atoms, the stronger. Usually, sharing electrons gives each atom a full valence shell and makes the resulting compound more stable than its constituent atoms are on their own. covalent bonds usually form between nonmetals. examples of covalent compounds include hydrogen (h 2), oxygen (o 2), carbon monoxide (co), ammonia (nh 3), water (h 2 o), and all organic compounds.
