because the gravity keeps the giants planets' gases from escaping.

For the same reason that our atmosphere on Earth does not escape into space - gravity.
It feels bad about how ugly it looks stupid. DAH
it's small size and low gravity
The gas giant planets have stronger gravity, which makes it harder for anything to escape, and are colder, which means that even with similar gravitational fields, gas molecules might not achieve escape velocity.
Mercury's gases escaped into space once
because if u have enough gas in one area it creates mass and causes it to stay in the gravity field of a planet
gravity keeps the giants planet's gasas from escaping
the planets have very strong gravitational pulls.
Jupiter has a gravity which is substantially greater than on Earth. The other gas giants have gravity which is similar to Earth's. Mercury, on the other hand, has a very weak gravity: around 38% compared to Earth. Also, being so close to the Sun it is blasted by the Solar wind. These two factors have stripped Mercury of its atmosphere.
No, the atmosphere is very thin. "Mercury has a very thin atmosphere consisting of surface atoms blasted off its surface by the Solar wind. Because Mercury is so hot, however, these atoms quickly escape into space. Thus, in contrast to the Earth and Venus whose atmospheres are stable, Mercury's atmosphere is constantly being replenished."
On top of the shelves is an air vent. By going up there after you have chosen "Sample Red mercury", you can enter the crawl space, and escape. :)
