How is the size of planet related to thickness of its atmosphere?

There is no simple relationship, but the general tendency is that more massive planets have more gravitational attraction, and are able to maintain a denser atmosphere. The amount of atmosphere a planet has may also depend on it closeness to the Sun / to the planet's star, and to its evolutionary history.

Why do outer planets have a thicker atmospheres than the inner planets?

Gravity is the force that keeps an atmosphere in place, surrounding a planet. Since there is no actual roof or container holding in the atmosphere, gas can always leak away into outer space, if it is not held in place by gravity. So the stronger the gravitational force, the more atmosphere can be retained. Large planets have a lot of hydrogen in their atmosphere, but hydrogen leaks away from smaller planets. Large planets attracted more gas when they were originally formed, as well. Remember that the solar system itself, and everything in it, originally condensed out of an interstellar cloud of gas and dust.

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.
