Lightning is an atmospheric discharge of electricity that occurs when there is a separation of charges within a cloud - it is what we see when a charge in a cloud earths itself to correct this separation. Lightning is accompanied by thunder, which is the sound made by the air surrounding a lightning bolt explaning due to the increase in temperature and pressure caused by the charge.
