Covalent bond definition is - a chemical bond formed between atoms by the sharing of electrons.
Covalent bonds. When none of the elements in a compound is a metal, no atoms in the compound have an ionization energy low enough for electron loss to be likely. In such a case, covalence prevails. As a general rule, covalent bonds are formed between elements lying toward the right in the periodic table (i.e., the nonmetals).
Note that this must occur between two nonmetal atoms in order for it to be a proper nonpolar covalent bond. That's a quick definition of nonpolar covalent bonds, but a closer examination of what it means for a bond to be covalent and what it means for a substance to be nonpolar will help you understand nonpolar covalent bonds in greater detail.

Covalent chemical bond - definition and types. What are the chemical bonds? Chemical bonds are defined as a set of interactions that take place in the electron shell of atoms, in order to join and form a molecule or a chemical stable compound.
covalent bond (kō'vā`lənt): see chemical bond chemical bond, mechanism whereby atoms combine to form molecules. There is a chemical bond between two atoms or groups of atoms when the forces acting between them are strong enough to lead to the formation of an aggregate with sufficient stability to be regarded as an
A coordinate covalent bond, also known as a dative bond or coordinate bond is a kind of 2-center, 2-electron covalent bond in which the two electrons derive from the same atom. The bonding of metal ions to ligands involves this kind of interaction. This type of interaction is central to Lewis theory. Examples
This sharing of atoms, instead of gaining or losing is called covalent bonding. And Carbon, since its atomic number is 6, and it has four electrons in the last shell has the most favourable structure for covalent bonding. Some Important Carbon Compounds with Covalent Bonds. Methane: Now let us take a look at covalent bonding in some carbon ...

Coordinate Covalent Bond. Some of life's most critical processes can be attributed to coordinate covalent bonds and the coordination compounds that contain them. For example, oxygen is distributed ...
Covalent bonds between identical atoms (as in H 2) are nonpolar—i.e., electrically uniform—while those between unlike atoms are polar—i.e., one atom is slightly negatively charged and the other is slightly positively charged. This partial ionic character of covalent bonds increases with the difference in the electronegativities of the two ...

Nonpolar bonds occur when atoms equally share electron pairs. Since only identical atoms (having the same electronegativity) truly engage in equal sharing, the definition is expanded to include covalent bonding between any atoms with an electronegativity difference less than 0.4. Examples of molecules with nonpolar bonds are H 2, N 2, and CH 4.
A covalent bond, also called a molecular 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.
covalent bond definition: the chemical bond formed between two atoms when they share electrons in pairs, so that each atom provides half the electrons...
With giant Covalent bonds, the bonds between layers are very strong, Diamond is an example of Giant Covalent bond of carbon. However, with a simple Covalent bond, the bonds between the atoms have a strong inter-molecular bond, but there are no bonds between the molecules, which is why it has a relatively low melting and boiling point.
Covalent Bond Definition. A covalent bond is a chemical bond that involves the sharing of electron pairs between two atoms. These electron pairs are known as bonding electron pairs, and they share these electrons to form covalent bond. This bonding is primarily found between nonmetals; however, it can also be observed between nonmetals and metals.
Ionic and covalent bonds are the two extremes of bonding. Polar covalent is the intermediate type of bonding between the two extremes. Some ionic bonds contain covalent characteristics and some covalent bonds are partially ionic. For example, most carbon-based compounds are covalently bonded but can also be partially ionic.
About Covalent and Ionic Bonds. The covalent bond is formed when two atoms are able to share electrons whereas the ionic bond is formed when the "sharing" is so unequal that an electron from atom A is completely lost to atom B, resulting in a pair of ions.
Covalent definition is - of, relating to, or characterized by covalent bonds. Recent Examples on the Web. The Chinese scientists built their version of an artificial muscle out of a special class of materials known as covalent organic frameworks (COFs), first synthesized in 2005.
To illustrate covalent bond formation based on the magnetic interaction, we examine the covalent bonds in hydrogen gas (like atoms) and hydrogen chloride (unlike atoms). A quantum theory of magnetism The two bonds between an oxygen and each of the hydrogen atoms in a water molecule are covalent bonds .
Pure covalent bonds (nonpolar covalent bonds) share electron pairs equally between atoms. Technically, nonpolar bonding only occurs when the atoms are identical to each other (e.g., H 2 gas), but chemists consider any bond between atoms with a difference in electronegativity less than 0.4 to be a nonpolar covalent bond.
