Ion engines typically use the gas xenon. Rocket exhaust is very hot, therefore before the rocket is safe from them, the exhaust would have to come out of the engine and past the long fuel/oxidizer tanks (which often contain fuel or oxidizer at 'cryonic temperatures'). It’s not a lot, but it’s enough thrust to move the spacecraft through space — remember we don’t have air resistance or anything when we’re off the earth.

Sure, that's not a lot if you think about that rocket engine you see firing up at the first liftoff, generating thousands upon thousands of pounds of thrust. In space, rockets zoom around with no air to push against. Rockets work in most space travel applications; The majority of interplanetary vehicles also employ.
