- Chemical bonding | Definition, Types, Examples | Britannica
Chemical bonding, any of the interactions that account for the association of atoms into molecules, ions, crystals, and other species When atoms approach one another, their electrons interact and tend to distribute themselves in space so that the total energy is lower than it would be in any alternative arrangement
- Ionic bond | Definition, Properties, Examples, Facts | Britannica
Ionic bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom Learn more about ionic bonds in this article
- Covalent bond | Definition, Properties, Examples, Facts | Britannica
Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms The binding arises from the electrostatic attraction of their nuclei for the same electrons A bond forms when the bonded atoms have a lower total energy than that of widely separated atoms
- Chemical compound | Definition, Examples, Types | Britannica
Chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements All the matter in the universe is composed of the atoms of more than 100 different chemical elements, which are found both in pure form and combined in chemical compounds
- Hydrogen bonding | Definition, Examples, Facts | Britannica
Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces Hydrogen bonds can exist between atoms in different molecules or in the same molecule
- Chemical reaction | Definition, Equations, Examples, Types - Britannica
A chemical reaction is a process in which one or more substances, the reactants, are converted to one or more different substances, the products Substances are either chemical elements or compounds A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products
- Polarity | Definition Examples | Britannica
Polarity, in chemical bonding, the distribution of electrical charge over the atoms joined by the bond While bonds between identical atoms such as two of hydrogen are electrically uniform in that both hydrogen atoms are electrically neutral, bonds between atoms of different elements are electrically inequivalent
- Double bond | Definition, Characteristics, Examples, Facts | Britannica
A double bond is a type of covalent bond in which two pairs of electrons (four electrons total) are shared between two atoms It is represented by two parallel lines (=) in a structural formula
- Single bond | Definition, Examples, Facts | Britannica
A single bond is a type of chemical bond in which two atoms share one pair of electrons, one electron from each atom This bond is represented by a single line (―) between the two atoms in structural formulas
- Features and types of chemical bonding | Britannica
Below is the article summary For the full article, see chemical bonding polar covalent bond In polar covalent bonds, such as that between hydrogen and oxygen atoms, the electrons are not transferred from one atom to the other as they are in an ionic bond Instead, some outer electrons merely spend more time in the vicinity of the other atom
