What is a colorless naturally occurring radioactive inert gaseous element formed by radioactive decay?
It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.
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.
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.
What element has no clothes?
The element that has no clothes is Uranium (symbol U). Uranium is a naturally occurring radioactive element with no specific connection to clothing.
Is the element silver radioactive?
NO!!! Because if it was, there would not be any silver jewellery/cutlery etc., about, because the radio-activity woulkd be dangerous.
