Which process explains why the terrestrial planets do not have hydrogen and helium in their atmospheres?

The terrestrial planets are less massive and therefore have less gravity. As a result, much of the lighter gases could escape, in the process of planet formation.

How does the chemical composition of the terrestrial planet atmospheres differ from the Jovian planets?
Jovian planets are less dense when they Are compared to terrestrial planets because they are Mostly composed of hydrogen gas.
Why do Jovian planets have a thicker atmosphere than the terrestrial planets?
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.
Why are the densities of the terrestrial and jovian planets so different?
The terrestrial planets are primarily composed of rock and the jovian planets are mostly gas (primarily Hydrogen). Rock has a higher density than Hydrogen, giving the terrestrial planets a higher density.
Why are gas giants larger than terrestrial planets?
The masses of the gas giants are greater, which would make them larger, and their gravity can hold more massive atmospheres. Due to limits on the compressibility of atmospheric gases, these atmospheres are very deep. The lower solar heating farther from the Sun also plays a role in allowing these planets to maintain a high percentage of their lighter gases (hydrogen, helium) than the inner planets. So, even without their atmospheres, the cores of gas giants would have greater diameters than the terrestrial planets. They are simply bigger planets.
Could you list the planets in order from the thickest to thinest atmospheres?
The terrestrial planets in order from the thickest to thinnest atmospheres Venus, Earth, Mars, and Mercury. Since the gas giants are almost entirely made of gas, it is difficult to determine where the atmospheres end.

Is hydrogen more abundant on terrestrial planets than on Jovian planets?
No, there is more hydrogen on the Jovian planets then the terrestrial ones.

Why are the four closest planets to the sun are of terrestrial nature and the last four are of gaseous-icy nature?
The gas giants and the terrestrial planets initially formed in similar ways, however, the powerful solar wind of the young sun stripped away the first atmospheres of the inner planets. The outer planets were less affected by this and so retained their thick atmospheres of hydrogen and helium. Today, the outer planets recieve much less heat from the sun than do the inner planets, allowing various ices to form.
What is the two main gases of the atmospheres of the outer planets?
amonia, hydrogen,

Differentiate Jovian planet from terrestrial planet?
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.
Why are the components of Jovian atmospheres so different from those of terrestrial planets?
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
Do the gas giants have thinner atmosphere than the terrestrial planets?
No. As the name gas giant implies, these planets are made largely of gas. They have extremely thick atmospheres.
