Canister of helium gas. Helium is a colourless, odourless, and tasteless gas that is the second lightest element in the periodic table. It is chemically inert, meaning it does not react with other elements under normal conditions. Helium is commonly used in balloons, blimps, and as a coolant for nuclear reactors and MRI machines. | |
