A double bond in chemistry is a chemical bond between two chemical elements involving four. In ethylene each carbon atom has three sp orbitals and one p- orbital. In molecules, with alternating double bonds and single bonds, p-orbital overlap can. These effects become more pronounced for the heavier elements.

In chemistry, Molecular orbital (MO) theory is a method for describing the electronic structure of molecules using quantum mechanics. Electrons are not assigned to individual bonds between atoms, but are treated as moving under the influence of the nuclei in the whole molecule. The spatial and energetic properties of electrons are described by quantum mechanics as molecular orbitals.

It is probably more useful to regard a chemical bond as an effect that causes certain atoms to join together to form enduring structures that have unique physical and chemical properties. So although the "chemical bond" (as a physical object) may be no more than a convenient fiction, chemical bonding, which leads to the near-infinity of substances (31 million in mid-2007), lies at.
