Mainly, the mass of a planet doesn't matter, considering many planets are made up of gas, and how in different situations, atmospheres can be destroyed (The Sun burnt off Mercury's Atmosphere). However, in some cases, the planet can be in a good situation on the galaxic map, and have great conditions for an atmosphere, such as Earth. In which case, the mass of an object can attract a smaller object, causing gravity. Therefore, the bigger the mass of a planet when in right and specific conditions, the more atmosphere it can attract, if there is any floating by the planet.
If it is bigger it will have more gravitational influence and therefore gather more gases.

Neptune is the planet that is most similar to Uranus in terms of size, composition, and atmosphere. Both planets are similar in size, composition, and are classified as ice giant planets.
The main features of planets include their size, composition, atmosphere, and orbital characteristics. Planets can be classified as terrestrial (rocky) or gas giants based on their physical makeup. They typically have a defined orbit around a star, and many possess atmospheres that can vary widely in thickness and composition. Additionally, planets may have moons, rings, and varying surface conditions, including temperature and geological activity.
The four inner planets, also known as the terrestrial planets, are Mercury, Venus, Earth, and Mars. Among them, Mercury has almost no atmosphere due to its small size and proximity to the Sun, which causes any gases to escape easily. Mars has a thin atmosphere, primarily composed of carbon dioxide, but it is much less substantial than Earth's. Venus has a thick atmosphere, so it does not fit the criteria of having almost no atmosphere.
Yes, the size of a planet can affect its atmosphere. Larger planets can hold onto gases more easily due to their stronger gravitational pull, leading to thicker atmospheres. Smaller planets may have thinner atmospheres or none at all if their gravity is too weak to retain gases.
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.

It is not a linear relation but, the larger the planet, the greater the gravity, the more it is able to attract and keep.

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.

The thickness of each planet can be measured by looking at the surface pressure - this is essentially related to the number of gas molecules for a given volume. A low pressure indicates a thin atmosphere, while a thicker atmosphere will have a higher surface pressure. You cant really give this for the four outer gas planets as they are made out of gas and have no real surface like the inner terrestrial planets. The atmospheres (and pressures) of the gas giants just get thicker the deeper you go into the planet. For Mercury, the surface pressure is near zero, there is no real atmosphere due to its small size and closeness to the sun. For Venus the atmosphere is thick, the pressure is some 93 bar (9.3 Mega-pascals - MPa or 9300 kilo-pascals - kPa) at the surface, where for earth it is about 1 bar (0.1 MPa or 100 kPa), so Venus' carbon dioxide atmosphere is 93 times that of earths. Mars has a thin carbon dioxide atmosphere of 0.064 bar or 6.4 kPa. 1 bar = 100 kPa = 0.1 MPa

Most planets have a solid surface, an atmosphere, and orbit a star. They also vary in size, composition, and distance from their star.
