It depends on what you mean by the pure form of Oxygen. Air is about 20% Oxygen. It comes as a molecule of two atoms of oxygen tied together. The chemical formula is O₂ but a single oxygen would be O. A single oxygen molecule does not exist in nature.
Thallium, discovered in 1861, does occur naturally, but not in its pure form.
Not naturally on Earth; calcium is too reactive with oxygen and water vapor to remain in a pure form outside a container.
Oxygen is a naturally occuring element, although people now have the technology to extract it from the air when they have a use for pure oxygen
No. The nobel gases and the rare earth metals (gold, platinum) occur as pure substances in nature because they are relatively unreactive. Most materials do not occur as pure substances (typically oxidized) and must be treated to be made pure.
Yes, oxygen is a chemical element.
No, it does not exist naturally in its pure form. Itexists in the combined form.

Germanium is a naturally occurring element, but does not occur in pure form on the Earth (only in compounds).
No - not naturally, it usually exist with other elements. To achieve a pure form, MnO2 needs to be heated with carbon to remove the oxygen.
Barium is a natural element. However, because it is so highly reactive, it does not occur naturally in a pure form.

There are a lot more than five. For example, all the alkali and alkaline earth metals are not found naturally in pure form but occur only in compounds. It's actually unusual for a metal to exist in pure form in nature; most of them occur only in compounds.
No. The nobel gases and the rare earth metals (gold, platinum) occur as pure substances in nature because they are relatively unreactive. Most materials do not occur as pure substances (typically oxidized) and must be treated to be made pure.
Yes, oxygen is a chemical element.
Is oxygen a form of mixture form, compound form, or mixture form
No
