A mixture ( it contains lots of gases.)
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
Foggy air is a mixture because it is composed of water droplets suspended in the air. It is not a pure substance with a fixed composition, so it does not qualify as an element or a compound.
Oxygen itself is not an example of a mixture, but rather an element. However, air, which is a mixture of gases including oxygen, can be considered an example of a mixture.
The pure nitrogen is a chemical element, gaseous at room temperature.
It is not one single element, but several.
Air is a mixture of gases.
Homogeneous mixture-uniform mixture of the element
No, air is not considered an element. Air is a mixture of different gases, primarily nitrogen and oxygen, along with small amounts of other gases like carbon dioxide and argon. Elements are basic substances that cannot be broken down further by chemical means.
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).

Foggy air is a mixture because it is composed of water droplets suspended in the air. It is not a pure substance with a fixed composition, so it does not qualify as an element or a compound.
Oxygen is an element and so can not be a mixture by itself. It can be part of a mixture, for example in air.
Air (clean or dirty) is a mixture, as it contains several different gases.
Oxygen itself is not an example of a mixture, but rather an element. However, air, which is a mixture of gases including oxygen, can be considered an example of a mixture.
Air is not an element. It is a mixture of gases. It's principal components are are nitrogen (~79%), oxygen (~21%), carbon dioxide (<0.1%) and argon.
The pure nitrogen is a chemical element, gaseous at room temperature.
because there are many elements and compounds in that make it up, eg, CO2 is a compound, but O2 is an element. This means its a mixture not an element.
