Examples of Gases - What Is a Gas? - Science Notes and Projects
gas, one of the three fundamental states of matter, with distinctly different properties from the liquid and solid states. The remarkable feature of gases is that they appear to have no structure at all.
Elements that exist as gases at room temperature and pressure are clustered on the right side of the periodic table; they occur as either monatomic gases (the noble gases) or diatomic molecules (some halogens, N₂, O₂).
A gas is a form of matter that does not have a defined shape or volume. Gases can consist of a single element, such as hydrogen gas (H 2); they may also be a compound such as carbon dioxide (CO 2) or even a mixture of several gases such as air.
