VIDEO Chemical Bond
A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds . The bond may result from the electrostatic force of attraction between atoms with opposite charges, or through the sharing of electrons as in the covalent bonds . The strength of chemical bonds varies considerably; there are "strong bonds" or "primary bond" such as metallic , covalent or ionic bonds and "weak bonds" or "secondary bond" such as Dipole-dipole interaction , the London dispersion force and hydrogen bonding . Since opposite charges attract via a simple electromagnetic force , the negatively charged electrons that are orbiting the nucleus and the positively charged protons in the nucleus attract each other. An electron positioned between two nuclei will be attracted to both of them, and the nuclei will be attracted toward electrons in this position. This attraction constitutes the chemical bond.
