Is air a mixture or a solution or a compound or an element? Air is a mixture of gases (and not a compound), about 78% being  nitrogen (an element) , about 21% oxygen (another element), and all  other gases present in much lesser amouâ¦nts. The remaining 1% is  made up of argon (0.93%), carbon dioxide (0.039% as of 2010) and  other trace gases (0.003%).
Air is a mixture of gases, which includes nitrogen, oxygen, carbon dioxide and water vapor (water in its gas form). Humidity refers to the amount of water vapor in air. All air contains at least some water vapor, but the amount of water vapor changes a lot from place to place and from time to time.
