  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.

  3. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    Individual molecules have strong bonds that hold the atoms together, but generally, there are negligible forces of attraction between molecules. Such covalent substances are usually gases, for example, HCl, SO 2, CO 2, and CH 4. In molecular structures, there are weak forces of attraction.

    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 ...

  5. Hydrogen bond - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_bond

    The resonance assisted hydrogen bond (commonly abbreviated as RAHB) is a strong type of hydrogen bond. It is characterized by the π-delocalization that involves the hydrogen and cannot be properly described by the electrostatic model alone.

  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.

    In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. [12] Alkene An unsaturated hydrocarbon that contains at least one carbon–carbon double bond. [13] The words alkene and olefin are often used interchangeably. Alkyne
