Mercury is the smallest of the eight planets, and is the only one not to have an atmosphere. This is due to its small size and close proximity to the sun.
Mercury is the only planet in the solar system without any significant atmosphere.
Mercury isn't large enough to have enough gravity to have an atmosphere. Mercury is a ball of nickel and iron, covered by a crust. There is no water or air on Mercury.
Mercury has no atmosphere.
What property controls the quantity of atmosphere in planets?
Space does not have an atmosphere. It is generally considered a vacuum. Planets and some moons have atmospheres.
the outer planets are gaseous and the inner planets are not
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.
atmosphere is made up of gases in all planets. But if you mean planets that are mostly atmosphere, then those are gas giants (Jupiter, Saturn, Neptune, Uranus)
What property controls the quantity of atmosphere in planets?
The atmosphere gets thicker and thicker as you go down; the planets basically consist mainly of atmosphere, though those planets are expected to have a solid core.
Mercury and the Moon do not have significant atmospheres. Mercury's thin exosphere mainly consists of atoms blasted off its surface by the solar wind, while the Moon has virtually no atmosphere, making them both airless bodies in our solar system.

If by gas you mean an atmosphere, there are no planets with an atmosphere anywhere similar to Earth.
It protects the inner planets from ultraviolet radiation

yes.
No
There are no planets in the Earth's atmosphere. The Earth's atmosphere is composed of different layers of gases, while planets are celestial bodies that orbit around a star. Planets exist outside of the atmosphere.
