Yes, steam is a compound. It’s made up of two atoms of hydrogen and one atom of oxygen.
In short, no. Steam is not a compound. Here’s a more detailed explanation:
Steam is water in its gas form. Water vapor is simply water molecules that have broken away from their liquid state and are now floating around in the air (or, in this case, inside your computer). Compounds are molecules made up of two or more elements chemically bonded together.
So, if steam were a compound, it would be made up of hydrogen and oxygen atoms bonded together – but it’s not. Steam is just water vapor.

Is Steam an Element Or Compound?
Steam is a compound made of two elements, hydrogen, and oxygen.
What Kind of Element is Steam?
Steam is a gas, specifically water vapor. It is produced when water boils or evaporates. When it cools, it condenses back into liquid water.
Is Steam an Element?
Steam is not an element. It’s a gas that’s produced when water boils.
Is Air a Compound?
No, the air is not a compound. It is a mixture of gases that are held together by atmospheric pressure. The main constituents of air are nitrogen (78%), oxygen (21%), argon (0.93%), and carbon dioxide (0.04%).

Is Water a Compound
Water is a compound because it contains two hydrogen atoms and one oxygen atom. The chemical structure of water is H2O. When water molecules are formed, they share electrons between the atoms to create covalent bonds.
This means that water is a polar molecule, with the hydrogen atoms being slightly positive and the oxygen atoms slightly negative.
Conclusion
No, steam is not a compound. A compound is a substance of two or more elements chemically combined in a fixed ratio. On the other hand, steam is simply water vapor – it’s just water in its gaseous state.
