A chemical bond is a long-term attraction between atoms, ions, or molecules that allows chemical compounds to form. Ionic bonds are formed by the electrostatic force of attraction between oppositely charged ions, while covalent bonds are formed by the sharing of electrons. Chemical bonds come in a variety of strengths; there are "strong bonds" or "primary bonds" like covalent, ionic, and metallic connections, as well as "weak bonds" or "secondary bonds" like dipole-dipole interactions, the London dispersion force, and hydrogen bonding.


Hydrogen bonding;  Dipole-dipole; Electromagnetic force


The negatively charged electrons orbiting the nucleus and the positively charged protons in the nucleus are attracted to each other due to a simple electromagnetic force.

An electron positioned between two nuclei will be attracted to both of them, while nuclei in this location will be attracted to electrons. The chemical connection is formed by this attraction. Because of the matter wave nature of electrons and their lower mass, they must occupy a much bigger volume than nuclei, and this volume occupied by the electrons holds the atomic nuclei in a bond that is relatively widely apart in comparison to the size of the nuclei.

Strong chemical bonds are usually related with the sharing or transfer of electrons between the atoms involved. Chemical bonds hold atoms in molecules, crystals, metals, and diatomic gases-indeed, most of the physical environment around us-together, dictating matter's structure and bulk properties.

Quantum theory can explain all bonds, but in reality, chemists can anticipate bond strength, directionality, and polarity using simplification criteria. Two examples are the octet rule and VSEPR theory. Valence bond theory, which incorporates orbital hybridization and resonance, and molecular orbital theory, which includes linear combination of atomic orbitals and ligand field theory, are more advanced theories. Bond polarities and their effects on chemical compounds are described using electrostatics.

Various types of chemical bonding

A chemical bond is an atom-to-atom attraction. This attraction can be explained by differences in the behavior of atoms' outermost or valence electrons. These actions blend effortlessly into one another in a variety of situations, leaving no visible distinction between them. Differentiating between distinct types of bonds, which result in diverse condensed matter properties, is still relevant and common.

One or more electrons (typically a pair of electrons) are dragged into the gap between the two atomic nuclei in the most basic conception of a covalent connection. The creation of bonds releases energy. Ionic bonds are strong (and so require high temperatures to melt), but they are also brittle, because ionic forces are short-range and do not easily bridge cracks and fractures. The physical features of crystals of classic mineral salts, such as table salt, are caused by this type of connection.

Metallic bonding is a less well-known type of bonding. Each atom in a metal provides one or more electrons to a "sea" of electrons that exists between numerous metal atoms in this sort of bonding. Each electron in this sea is free (because to its wave nature) to be linked with a large number of atoms at the same time.

The bond is formed when metal atoms lose their electrons and become somewhat positively charged, but the electrons stay attracted too many atoms without being part of any one of them. Metallic bonding can be thought of as an extreme case of electron delocalization over a huge system of covalent connections in which every atom is involved. This form of connection is frequently extremely strong (resulting in the tensile strength of metals). Metallic bonding, on the other hand, is more collective in character than other types, allowing metal crystals to deform more easily because they are made up of atoms attracted to one other but not in any particular direction. Metals become malleable as a result of this.

Metals' usually excellent electrical and thermal conductivity, as well as their lustrous sheen that reflects most wavelengths of white light, are due to the cloud of electrons in metallic bonding.
