Detailed explanation-1: -Double bond is a type of chemical bond in which four electrons are shared between two atoms in a molecule. In a double bond two pairs of electrons (four electrons) are shared between two atoms. Example: Formation of Oxygen molecule.
Detailed explanation-2: -When electrons are shared between two atoms, they make a bond called a covalent bond . Because two atoms are sharing one pair of electrons, this covalent bond is called a single bond . These two atoms can do the same thing that the H atoms did; they share their unpaired electrons to make a covalent bond.
Detailed explanation-3: -A double bond is two horizontal lines between two atoms in a molecule which represent 2 pairs of electrons or a total of 4 electrons. A double bond is relatively stronger and shorter than a single bond, however, it is less stable.
