Oxygen is the gas in air that unites with many metals. It readily reacts with metals to form metal oxides through oxidation reactions. This process is fundamental in various applications, including corrosion and combustion, where metals react with oxygen to produce heat and light.

Brass gets discoloured in air because of the presence of which of the gases in air?
Brass gets discolored in air because of the presence of sulfur gases, like hydrogen sulfide, which react with the metal to form a dark layer of tarnish or patina on its surface.
Does the air contain non-metal elements?
Air contains approximately 78% nitrogen, 21% oxygen and the final 1% is made up of argon, carbon dioxide and trace amounts of other gases. There is a possibility that air could also contain many bacteria and viruses from humans sneezing.
Why moist air and acidic gases are not good for metals?
Moist air and acidic gases can accelerate the corrosion process in metals due to the presence of water and corrosive compounds. Moisture creates an electrolyte that facilitates the flow of electrons, leading to oxidation and deterioration of the metal surface. Acidic gases, such as sulfur dioxide or carbon dioxide, can react with moisture to form acids that further corrode the metal. Together, these conditions can significantly shorten the lifespan of metal structures and components.
How many known gases are there?
There are over 50 known gases, including common gases like oxygen, nitrogen, and carbon dioxide, as well as more rare gases like xenon and krypton. These gases can exist in various forms, such as elemental gases, compound gases, and noble gases, each with its own unique properties and uses.
Why do noble gases in balloon float in air?
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
