  2. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. The types of strong bond differ due to the difference in electronegativity of the constituent elements.

    A bond that involves the sharing of electron pairs between atoms. The stable balance of attractive and repulsive forces that occurs between atoms when they share electrons is known as covalent bonding. A diatomic hydrogen molecule, H 2 (right), is formed by a covalent bond when two single hydrogen atoms share two electrons between them ...

  4. Cohesion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Cohesion_(chemistry)

    Water, for example, is strongly cohesive as each molecule may make four hydrogen bonds to other water molecules in a tetrahedral configuration. This results in a relatively strong Coulomb force between molecules. In simple terms, the polarity (a state in which a molecule is oppositely charged on its poles) of water molecules allows them to be ...

  5. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    Bonds with one or three electrons can be found in radical species, which have an odd number of electrons. The simplest example of a 1-electron bond is found in the dihydrogen cation, H + 2. One-electron bonds often have about half the bond energy of a 2-electron bond, and are therefore called "half bonds".

  6. Ionic bonding - Wikipedia

    en.wikipedia.org/wiki/Ionic_bonding

    In simpler words, an ionic bond results from the transfer of electrons from a metal to a non-metal to obtain a full valence shell for both atoms. Clean ionic bonding — in which one atom or molecule completely transfers an electron to another — cannot exist: all ionic compounds have some degree of covalent bonding or electron sharing.

  7. Metallic bonding - Wikipedia

    en.wikipedia.org/wiki/Metallic_bonding

    The strong bonding of metals in liquid form demonstrates that the energy of a metallic bond is not highly dependent on the direction of the bond; this lack of bond directionality is a direct consequence of electron delocalization, and is best understood in contrast to the directional bonding of covalent bonds.

  9. Ligand - Wikipedia

    en.wikipedia.org/wiki/Ligand

    The bond order of the metal ligand bond can be in part distinguished through the metal ligand bond angle (M−X−R). This bond angle is often referred to as being linear or bent with further discussion concerning the degree to which the angle is bent. For example, an imido ligand in the ionic form has three lone pairs.
