Nitrogen and Oxygen are both elements on their own. But when you combine them with Water vapor, Argon, and Carbon dioxide you get the mixture know as air. (There are 9 other chemical elements and compounds found in air but they are almost all trace amounts. All of these chemicals and compounds combined make up less then 0.0007100% of air)
Definition of compound - A substance formed from two or more elements chemically united in fixed proportions.
Definition of mixture - The product of the random distribution of one substance through another without any chemical reaction.
Definition of element - Each of more than one hundred substances that cannot be chemically inter-converted or broken down into simpler substances and are the primary building blocks of matter. Each element is distinguished by its atomic number, i.e., the number of protons in the nuclei of its atoms.
Nitrogen dioxide in a COMPOUNDm because it is a chemical combination of nitrogen and oxygen. (NO2)
It is a solution of several gasses, the most abundant of which are nitrogen and oxygen.
Mixture
Air is a mixture of about 80% nitrogen, and about 20% oxygen, with small amounts of other substances (such as carbon dioxide and water vapor).
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
Neither. Oxygen is an element. In the air it forms a mixture with nitrogen, carbon dioxide, etc.

Oxygen is an element.
oxygen is a element ! :)
Clean air is actually a mixture! It is made out of various elements such as oxygen, hydrogen and nitrogen.
Air is a mixture, made mostly of the elements nitrogen and oxygen. It also has some other gases, such as argon (element), carbon dioxide (compound), and water (compound).
No, it is a compound of the elements nitrogen and oxygen.
It is a mixture MAINLY of elements- nitrogen, oxygen, argon. However, there are a small number of compounds in the mixture- such as carbon dioxide (compound of carbon and oxygen)
Oxygen is a chemical element.
It is a solution of several gasses, the most abundant of which are nitrogen and oxygen.
An element
Nitrogen oxide is a compound because it is an atom of Nitrogen and an atom of Oxygen bonded together. It is not a mixture or just a single element.
