    What??? Electrons do not explode away from negative charges, they are just repelled away

    Negative, crewgurl. (No pun intended.) A grenade uses chemical explosives or other payloads such as phosphorus. Detonation is triggered by either impact or time-delay fuses.

    The energy of the explosion comes from the electrons, which on explosion give away energy when forming more stable (less energetic) molecules. BUT a grenade doesn't explode because of the electromagnetic repulsion between the electrons.

    I assume that this is what you were after. (?)

    Explosives work by using a chemical reaction that turns a solid into a gas very quickly. The gas occupies more than a thousand times more volume than the solid at normal temperatures and pressures and so a great deal of pressure and expansion is generated and this is the explosion. In general the atoms are the same size before and after the explosion it is just that the chemical forces bonding the solid no longer hold them together and they can move freely.
