Americium is an artificial chemical element, man made !
copper is a naturally occuring element
Americium is primarily found in nuclear reactors and nuclear waste, as it is a man-made element produced during nuclear reactions. It may also be present in very small amounts in smoke detectors, as they contain a small amount of americium-241 for ionizing radiation detection.
Boron is a naturally occurring element that is found in the earth's crust. It can be found in compounds in rocks, soil, water, and plants.
Rhenium is both man made and found naturally. Natural rhenium deposits are found in Arizona and Utah.
No, americium-241 is not naturally occurring. It is a radioactive element that is primarily produced as a byproduct of nuclear reactions in nuclear reactors or during the decay of plutonium.
it is naturally found
Phosphorus is a naturally occurring element found in mineral deposits and living organisms. It is not man-made.

Well including uranium and a few others that are commonly man-made but are actually natural there are about 92. After and including Americium they are man-made and named for places or people, for example 99 is Einsteinium.
Thulium is a naturally occurring element that is found in the Earth's crust. It is not man-made.
Resources that are found naturally and not man-made
It is not know to be naturally produced but is rather an man-made chemical synthesised in labs.
Oxygen is naturally found in the earth's atmosphere and is a chemical element that is not man-made.
It is made from clay found naturally. Heated up into the shape of a pot.
