What else can I help you with?
Is thulium man made?
No. It is a "Rare Earth"- found only in trace amounts, but naturally occurring.
What element is the lightest actinide that occurs naturally on earth?
The lightest naturally occurring actinide on Earth is thorium, which has the atomic number 90. It is a naturally occurring radioactive element found in small amounts in soil and rocks.
Is iron a naturally occurring element?
Yes, iron is a naturally occurring element found in the Earth's crust. It is one of the most abundant elements on Earth and is commonly found in minerals such as hematite and magnetite.
Is sodium naturally occurring or synthetic?
Sodium is a naturally occurring element that is found in the Earth's crust and in various minerals. It is commonly obtained by the electrolysis of salt water.
Is lithium manmade?
No. Lithium is a naturally occurring element.
Is phosphorus a naturally occurring or man made?
Phosphorus is naturally occurring. It is found in rocks
Is boron Man made or Natural?
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.
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.
Is diamond natural or man-made?
Diamonds are a naturally occurring substance found deep in the earth's crust.
What is the rarest naturally occurring element?
Astatine is considered the rarest naturally occurring element on Earth. It is extremely radioactive and is typically only found in trace amounts in uranium and thorium ores.
Is argon radioactive and synthetic?
Neither. Argon is naturally occurring noble gas
Is boron man made or naturally occurring?
It is a natural occurring element in the noble gas group.
