Air is a MIXTURE of COMPOUNDS and ELEMENTS.
The compounds being :-
Carbon dioxide (CO2)
Water (H2O)
The elements being :-
Oxygen (O2)
Nitrogen (N2)
Helium (He)
Neon(Ne)
Argon (Ar)
Ozone (O3 ; At high altitudes).
This is NOT a complete list of compounds and elements that form the atmosphere. There are many more trace compounds and elements present.

What is the element number of water?
Contemporary science does not consider water to be an element.
What is a mixture a science vocabulary is called what?
A mixture in science is called a heterogeneous mixture when its components are not uniformly distributed.
Why is water a compound and not an element or mixture?
Water is a compound because it COMBINATION of Hydrogen atoms and Oxygen atoms. They are combined cavalently, (electron sharing). Water is NOT an element , because it is a COMBINATION of two elements. viz. hydrogen and oxygen . Water is NOT a mixture, because electrons would NOT be chared in a mixture. Hydrogen and Oxygen gases would just remain as gases. The chemical formula for water is ' H2O' . This tells us that there are two atoms of hydrogen and one atom of oxygen. Structurally they are combined as 'H-O-H '. Possible chemical names for 'WATER' are ' Hydrogen Oxide', Dihydrogen monoxide'. However, names like these are never used. Water's name in science, like everywhere else , is just 'WATER'.
Give an example of an mixture and a compound?
compound you cants separate and misture you can separate ----------- A chemical compound can be separated in elements by a chemical or physico-chemical method: for example we can obtain Na and Cl from NaCl by electrolysis. A mixture can be separated in components by mechanical procedures; for example we can obtain iron from garbage by an electromagnetic method.
What is a mixture of two substances in which the molecules of the substances are evenly mixed?
A Compound mixture. I think it is called homogeneous... <>
Is dust element compound or mixture?
It is a mixture according to my science teacher.
Is water a mixture or a compound is science?
Water is a pure compound -- all of it is one kind of molecule: H2O.
Is cereal a compound in science?
Cereal is NOT a compound, NEITHER a homogeneous mixture, BUT yes, it is a heterogeneous mixture
Is dust an element compound or mixture?
Dust is typically a mixture of various particles including dirt, pollen, skin cells, and debris. It is not classified as an element or compound because it is made up of different substances that are physically combined.
Is a substance a mixture a compound or an element?
Liquid air is a mixture not a compound. As we know that air is a mixture of different gases. It contains 78% nitrogen and 21% oxygen and remaining 1% is comprising various other gases. The process of preparing liquid air does not involve any chemical reaction and hence no compound is formed. It is basically a physical process involving compression of air as well as cooling simultaneously. Thus liquid air remains a mixture.
Is mud an element or a compound or a mixture?
Clay is in fact a mixture. I know so because I learned that in science class today. I'm not a phony- baloney, so you can take my word
Is coffee a mixture a compound or a solution?
It is a solution if you would have done your science homework you would know this.
When we were little why are we taught or told that water is a element when in reality its a compound?
Science is changing every day.
How do you know what's your element?
Are you asking how you know what element a given sample of material is (assuming that it is, in fact, an element and not a compound or mixture)? If so, there are various chemical tests you could run, but in actual practice it's almost always easier to do a spectrographic analysis. If you're asking about "your element" in some sort of new-agey astrology analogue... beats me, I only know about real science.
Is flourine an element or a compound?
element because it is on the periodic table of elements which you can seeon google images. wow i do learn a lot from science at school... :) hope it helps you!
Is a pencil a compound or mixture?
Yes it is a compound. I am a Science teacher at Brownwell High School.
What is a mixture a science vocabulary is called what?
A mixture in science is called a heterogeneous mixture when its components are not uniformly distributed.
