Phosphorus is naturally occurring. It is found in rocks
yes. Phosphorus-32 is synthetically produced. but only for research reasons.
sun,,??maybe..
They are isotopes of Phosphorus and show similarity in their physical properties to that of Phosphorus.
Thallium, discovered in 1861, does occur naturally, but not in its pure form.

Phosphorus is a naturally occurring element, it's used by plants to speed up growth
It DOES occur naturally. It is an ore. It is not man made.

Pure phosphorus is extracted my chemical means and can be bought, but it does not occur in nature.
sea minerals are an important source
