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.
It is an element.
No. An element is a pure substance made of only one kind of atom. A compound is a pure substance made of two or more kinds of atom.
It is a pure element, though if you are talking about sulfur in its natural form (S8), then yes it is a pure compound.
Air is a mixture of different gases, including nitrogen, oxygen, carbon dioxide, and others, rather than a compound or element. It is not a pure substance but a combination of gases that makes up Earth's atmosphere.
The former.
Pure air is a homogeneous mixture of gases, primarily nitrogen and oxygen. It is not a compound or element as it consists of a blend of different gas molecules.
A pure element or a pure compound are homogeneous.
Californium is a pure element.
Plutonium is a pure chemical element.
Pure gold is an element, not a compound. It is composed of only one type of atom, which is gold.
No, it is a pure element
Gold is a pure substance (element), water is a compound, steel is an alloy, and air is a mixture of gases.
pure element
Iodine is a compound. Water is a compound composed of hydrogen and oxygen. Calcium is a pure element. Air is a mixture of different gases.
Platinum is an element, so it is "pure".
A pure substance is an element or a compound.
