Many planets have an atmosphere that is poisonous, at least for us. All the gas giants, for a start. Mercury has almost no atmosphere. This would not exactly be poisonous, but it isn't exactly health, either... You would still need to keep your spacesuit on, if you venture outside the ship. Venus is also toxic for us - and, it is extremely hot. Mars' atmosphere isn't fit for humans, either.
A planet with a deep and massive atmosphere is typically referred to as a gas giant. Gas giants are composed mainly of elements such as hydrogen and helium and have thick atmospheres that can extend for thousands of kilometers. Jupiter and Saturn are examples of gas giants in our solar system.
A planet with a deep, massive atmosphere is typically referred to as a gas giant. Gas giants like Jupiter and Saturn are characterized by their thick atmospheres primarily composed of hydrogen and helium, with smaller amounts of other gases. These planets lack a solid surface and have extensive layers of gas envelope.
Venus has a thick, cloudy atmosphere that extends about 600 miles deep. The clouds are composed of sulfuric acid droplets and cover the entire planet, making it difficult to see its surface from space.
Jupiter is considered the gassiest planet in our solar system. It is composed mostly of hydrogen and helium, with small amounts of other gases. Its massive size and gravity contribute to its ability to retain a thick atmosphere of gases.
Mercury is the least massive planet in our solar system.
A "Gas Giant" planet.
That is commonly called a gas giant.

Mercury has no real atmosphere as the planet is too close to the sun and is not massive enough.
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
The more massive planet is more likely to maintain its atmosphere because its stronger gravity can hold onto the gases in its atmosphere better. The gravitational pull of the heavier planet can prevent gases from escaping into space, resulting in a more stable atmosphere compared to the lighter planet.
Venus and the four outer planets all have a very thick and massive atmosphere.
The mass of the planet. It's not clear cut, since there has to be gas around in the area to provide the atmosphere, but the planet (or moon) need to be massive enough to provide sufficient gravity for the gas molecules not to escape into space.
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.
