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.

What kind of elements does aluminum combine with?
Aluminum combines chemically into binary compounds mostly with nonmetal elements, but aluminates, which contain oxygen, aluminum, and another metal element are also important minerals practically.
Are molecular compounds usually non-metals?
Yes, most molecular compounds do not contain metals. (The term "nonmetal" properly applies only to elements, not compounds.)
Is SO3 a nonmetal or a metal?
SO3 is a compound and therefore is neither a metal nor a nonmetal, because these are types of chemical elements, not of compounds. This particular compound consists of two nonmetal elements, sulfur and oxygen.
What are the properties of nonmetal elements?
element that is not metal
What is main ingredients of the salts?
Salts contain a cation (metal or ammonium) and an anion (a nonmetal etc.).
