The three main characteristics of the terrestrial planets (Mercury, Venus, Earth and Mars) are that they are composed of mainly rock, they are close enough to the sun to have lost the hydrogen and helium all planets were originally made of, and they are much smaller than the gas giants because of this loss of gases.
Gas giants (Jupiter, Saturn, Uranus and Neptune) are planets which are far enough away from the sun's heat to hold onto all of their gases of hydrogen and helium. Therefore, they are much larger than the terrestrial planets.

Terrestrial planets will have a breatheable atmosphere like earth, available water and at least flora (and hopefully, fauna).
The giant gas planets like Jupiter and Saturn are very dense, high gravity planets and consist mainly of gases. Life of any sort as as we know it cannot exist.

e. They all have substantial atmospheres. Mars has a very, very thin atmosphere, Mercury has no atmosphere at all.
