Petroleum is a potential.
yeah that's my guess.
The answer is:
The arrangement of the Atoms
Their ability to lose that electron easily. This property is electronegativity. Once that electron is taken away, the atom becomes an ion with a charge of +1. The ion would be much more stable than the atom, because once the electron is lost, the shell underneath will already have 8 electrons that resembles the configuration of a noble gas.
