Chemical Bonds

Chemical bonds create the attractive forces between atoms in a molecule, where positively charged nuclei are attracted to a region of increased electron density along the bond. Ionic bonds are formed through electrostatic interaction while covalent bonds occur through the sharing of electrons. Single bonds are formed from σ orbitals, while double and triple bonds are formed by combinations of σ and π orbitals. Use Wolfram|Alpha to inspect chemical bond information.
