Air was considered a “pure” element, but in fact the air that’s all around us is made up of a variety of gases: primarily nitrogen and oxygen, with almost 1% argon and even smaller amounts of carbon dioxide and other elements such as krypton and helium. These include sulfur, magnesium, calcium, and potassium. Each world has more than 20 groups with 5 puzzles each. Other elements are found in small amounts, too. The Composition of Air: Air is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and other gases in meager amounts. Oxygen is the second most abundant gas in the atmosphere but the third most abundant chemical in the universe, after hydrogen and helium. Which statement best describes these three components of air? The main constituents of air are Nitrogen and Oxygen. It is a standard scientific unit of measurement. Nitrogen composes ~79% while oxygen makes up the other ~21%. It's also present in the base pairs that make up nucleic acid, making it an essential component for life. What Elements Make Up the Air We Breathe?

Air is nearly 99 percent nitrogen and oxygen. Standard Dry Air is the composition of gases that make up air at sea level. It does not include water vapor because the amount of vapor changes based on humidity and temperature. The nineteenth-century chemist states, "The atoms of this element have a low electron affinity and will replace hydrogen atoms when placed into water. A)They are all classified as pure substances. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
