Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
Jupiter, Saturn, Uranus and Neptune are all Jovian planets.
The four Jovian planets in our solar system are Jupiter, Saturn, Uranus and Neptune. The four terrestrial planets are Earth, Venus, Mars and Mercury. The difference between the Jovian planets and the terrestrial planets is that Jovian planets are enormous and made of gasses and ices while terrestrial planets are relatively small and made of rocks and metals. Other differences are that terrestrial planets have high densities, rotate slowly, have no moons or magnetic fields and have thin atmospheres (Earth is an exception because it has a moon and a magnetic field), while Jovian planets have low densities, rotate rapidly, have many moons and a magnetic field and have thick atmospheres.
Terrestrial planets, like Earth and Mars, are small, rocky, and have solid surfaces. They have thin atmospheres and are closer to the sun. Jovian planets, such as Jupiter and Saturn, are gas giants with thick atmospheres of hydrogen and helium. They are much larger, have no solid surfaces, and are farther away from the sun.
Jovian planets are large gas giants composed mostly of hydrogen and helium. They have thick atmospheres with strong winds, and lack solid surfaces. Jovian planets are typically far from the Sun and have numerous moons and ring systems.
They are different because terrestrial planets is any of Earth like planets including: Mercury, Venus, Mars, and Earth. However jovian planets are the Jupiter like planets including: Jupiter, Saturn, Uranus, and Neptune
Terrestrial planet atmospheres are primarily composed of gases like nitrogen and oxygen, with small amounts of carbon dioxide and other trace gases, while Jovian planet atmospheres consist mostly of hydrogen and helium, along with traces of methane and ammonia. Terrestrial planets have thinner atmospheres compared to Jovian planets, which have massive, thick atmospheres made up of mostly hydrogen and helium.
Jovian planets are gas giants made mostly of hydrogen and helium, while terrestrial planets are rocky planets with solid surfaces. Jovian planets are much larger in size and have thick atmospheres, while terrestrial planets are smaller and have thinner atmospheres. Jovian planets have many moons and ring systems, while terrestrial planets have fewer moons and no rings.
Jovian planets do not have a solid surface, therefore their atmospheres are thick all the say to where their surface would be. Their atmospheres have more gasses than those surrounding terrestrial planets.
Terrestrial planets are rocky, smaller, and closer to the Sun, such as Mercury, Venus, Earth, and Mars. Jovian planets are gas giants, larger, and further from the Sun, such as Jupiter, Saturn, Uranus, and Neptune. Jovian planets have thick atmospheres mainly composed of hydrogen and helium, while terrestrial planets have thin atmospheres and solid surfaces.

Terrestrial planets are small, rocky, and have solid surfaces, while jovian planets are large, gaseous, and lack solid surfaces. Jovian planets also have thick atmospheres composed mostly of hydrogen and helium, while terrestrial planets have thinner atmospheres with varying compositions.
Jovian planets are large gas giants composed mostly of hydrogen and helium. They have thick atmospheres with strong winds, and lack solid surfaces. Jovian planets are typically far from the Sun and have numerous moons and ring systems.
While terrestrial planets are made of rock and have gases in the atmosphere, jovian planets are made almost entirly of gases. If an atmosphere is made of gases in a planet, then the atmosphere of the planets with more gases will be thicker.
Jovian planets are large and gaseous, with thick atmospheres composed mainly of hydrogen and helium. They have low densities and lack solid surfaces. Jovian planets are typically located farther from the sun than terrestrial planets.
