  • 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
  • Chemical bonding - Hydrogen Bond, Intermolecular Forces, Molecules . . .
    Chemical bonding - Hydrogen Bond, Intermolecular Forces, Molecules: The interactions described so far are not limited to molecules of any specific composition However, there is one important intermolecular interaction specific to molecules containing an oxygen, nitrogen, or fluorine atom that is attached to a hydrogen atom This interaction is the hydrogen bond, an interaction of the form A
  • 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
  • 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
  • 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
  • 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
  • Chemical bonding - Polarization, Intermolecular Forces, Covalent Bonds . . .
    Chemical bonding - Polarization, Intermolecular Forces, Covalent Bonds: There are three main properties of chemical bonds that must be considered—namely, their strength, length, and polarity The polarity of a bond is the distribution of electrical charge over the atoms joined by the bond Specifically, it is found that, while bonds between identical atoms (as in H2) are electrically uniform
  • Chemical energy | Definition Facts | Britannica
    What happens to chemical bonds when a chemical reaction takes place? According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds Energy is absorbed to break bonds, and energy is evolved as bonds are made
