Explain why the outer planets did not lose the light gases in their atmospheres?

In order for gas to leave a planet it needs to be hot enough and to overcome the planet's gravity. The outer planets are colder and are very massive in comparison to Earth.

Did outer planets lose the light gases in their atmosphere?
no.
Why are gaseous planets larger than rocky planets like earth?
Planets which began in dense matter regions have greater mass, and are able to hold onto their large, deep atmospheres of light gases like hydrogen and helium. (Jupiter's diameter is mostly atmosphere, while Earth's atmosphere is relatively shallow at about 1% of its diameter.)
Do planets emit light or reflect light?
Planets reflect light.
What planets produce their own light?
No, planets don't give off light, stars did.
Do Planets and their moons emit light?
No. Planets and moons reflect light.
Why have the Jovian planets retained their atmospheres?
Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
What does a star's atmosphere do to some light?
Stars do not normally have atmospheres, some planets do
How do planets make their own light?
In general, planets don't make their own light. Rather, they reflect the light of the sun. It is possible to see lightning in the atmospheres of some planets, but that probably doesn't count.
Why do different planets have different atmospheres?
All the sun's planets probably had similar atmospheres when they first formed, billions of years ago. The most common gases were the light gases, hydrogen and helium, with smaller amounts of oxygen, nitrogen and other gases. The immense gravity of the giant planets, Jupiter, Saturn, Uranus and Neptune, was able to hold the hydrogen and helium, which remain the predominant gases in their atmospheres, along with methane formed by the combination of hydrogen with free carbon. However, hydrogen and helium gradually escaped from the atmospheres of the smaller planets, where gravity is insufficient to hold the light gases permanently. Even the heavier gases, such as oxygen and nitrogen, as well as carbon dioxide and water vapour, can gradually escape from smaller planets, such as Mars and Mercury. So, these planets now have quite thin atmospheres. The Moon and other small bodies in the solar system have essentially no atmosphere. In our solar system, only the Earth and Venus are the right size to lose most of the light gases, while retaining gases such as oxygen, nitrogen, carbon dioxide and water vapour.

What can the sun do that the moon and other planets cant?
The sun burn gases and is static, where as the moon and the other planets move and are not sources of light.
What happens when starlight hits the planets?
The same thing that happens to any other light; some of it is absorbed by the atmospheres and surfaces of the planets while some is reflected back into space. Starlight is too dim to see objects by it.
