its a mixture made of primarily nitrogen as well as O2 and CO2 along with some other trace elements.
The pure nitrogen is a chemical element, gaseous at room temperature.
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.

Uranium is a natural chemical element, a pure element.
Neither. Oxygen is an element, which is a pure substance and not a mixture.

If you are talking about the gas we breath in the air, it's a compound. Pure oxygen as a gas exists as a molecule. Oxygen as an element, is unstable and as far as I know doesn't exist as a single element in nature. It will always occur in combination with something else, such as H2O or O2.
No. It will be a homogeneous mixture of gases.
Copper metal is an element and thus a pure substance.
Gold is an element, not a compound or mixture. It is a pure substance made up of only gold atoms.
