Yes, all the ones in our solar system seem to. Observations of planets in other systems seem to be, also. Theoretically, any planet with a high enough gravity to qualify as a gas giant can retain gases that are poisonous to us, such as hydrogen and helium. Nice article in the link below.
What else can I help you with?
Do Gas Giants have atmospheres that are thousands of miles or kilometers thick?
Yes.
A sentence for gas giants?
A sentence for gas giants is: There are four gas giants in the solar system, which are Jupiter, Neptune, Saturn, and Uranus. Another sentence is: The gas giants are mainly composed of various different gases.
What are the outer plantes made out of?
The outer planets, also known as gas giants, are primarily composed of hydrogen and helium. These planets have thick atmospheres made up of gases like methane, ammonia, and water vapor. Beneath their atmospheres, gas giants have dense layers of metallic hydrogen and rock.
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.
What is the composition the gas giants?
gas.
Do the gas giants have thick or thin atmospheres?
Gas giants such as Jupiter and Saturn have thick atmospheres composed mainly of hydrogen and helium. These atmospheres can extend thousands of kilometers deep into the planets' interiors.
Which gas in atmospheres of some gas giants gives them a blue color?
methane gas
What gases are found in the atmospheres of gas giants?
Hydrogen and Helium
Why can't the atmospheres of the gas giants just escape into space?
Gravity.
Gas giants have atmospheres composed primarily of hydrogen and what else?
Helium
Do Gas Giants have atmospheres that are thousands of miles or kilometers thick?
Yes.
Why do all the gas giants have thick atmospheres?
gravity keeps the gas giants planets gases from escaping so they have thick atmosphere
How does the composition of earths atmosphere differ from the composition of the atmospheres of the gas giants planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
What do all gas giants have that terrestrial plants do not have?
Gas giants have enormous atmospheres, it may be said they consist only of atmosphere. They have a large mass, and they have rings.Gas giants have enormous atmospheres, it may be said they consist only of atmosphere.

Why would the gas giants be made of gas when they are so cold?
The gas giants are composed of hydrogen and helium, which can remain in a gaseous state at extremely low temperatures, even lower than thous found in the atmospheres of the gas giants. In reality, though, most of the volume of the gas giants is not gas. Deep within the atmospheres of these planets the enormous pressure renders the hydrogen and helium into a supercritical state, which is characteristics between those of a liquid and a gas. Even deeper the hydrogen enters an exotic metal-like state. The interiors of the gas giants are very hot.
Why cant the atmospheres of gas giant escape into space?
gravity keeps the giants planet's gasas from escaping
