Francium occurs naturally, although extremely rare. It can and is made in labs. Although it is considered a naturally occurring element, there is only about one ounce of it in the Earth's crust at any one time. Scientists reproduce it in labs so they can study it, ect. So little is known about Francium now; if we didn't reproduce it in labs we would know next to nothing about it.
What else can I help you with?
Is another word for not occur ing naturally?
"Synthetic" could be another word for something that does not occur naturally.
Mendelevium does it occur naturally in nature or is manmade?
Mendelevium is a manmade element and does not occur naturally in nature. It is produced by bombarding einsteinium with alpha particles in a particle accelerator.
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
Does steel occur naturally?
no, steel is one of many manmade alloys. the closest natural material to steel are nickel-iron meteorites.
What is a naturally occuring isotope?
It is an isotope that occurs in nature, and is not manmade. Isotopes, by the way, are atoms that have the same number of protons, but different number of neutrons. The atomic number is the same, but atomic weight (or mass) is different. For instance, Carbon can be Carbon 10, 11, 12, or 14. They are all carbon.
What is a artificial?
Artificial means that it does not occur naturally. If something is artificial it is manmade.

Does a radioisotope of gold occur naturally?
No, gold has only one naturally occurring isotope and it is non-radioactive.
What is the use of isotope of oxygen?
The isotopes are not manufactured for specific uses, they occur in nature naturally.

Does phosphorus 32 occur naturally?
No, phosphorus-32 is a radioactive isotope of phosphorus and is not found naturally in significant amounts. It is typically produced in nuclear reactors or particle accelerators.
Is zinc manmade or naturally occurring?
Both. Zinc can be found in nature and also can be manmade.
Is tar manmade?
No, it is a naturally occurring petrochemical.
Are minerals manmade?
No. By definition a mineral is naturally occurring.
