  • 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
  • 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
  • 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
  • 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
  • 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
  • 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
  • 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
  • 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
  • Molecule | Definition, Examples, Structures, Facts | Britannica
    Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance Learn more about the properties and structures of molecules in this article
  • 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
