Why is there naturally occurring technetium on earth?
Natural technetium exist only in infinitesimal traces in some uranium deposits.
Which element is the heaviest actininde that occurs naturally on earth?
Uranium is the heaviest naturally occurring actinide.
What is the heaviest actinide that occurs naturally on Earth?
Uranium
Which two actinides occur naturally?
Uranium and thorium are the two actinides that occur naturally in the Earth's crust. They are found in low concentrations and have important roles in various nuclear reactions and processes.
Does plutonium have an ore?
Plutonium has no ores; plutonium exist naturally in extremely traces in uranium ores.
What atom is found naturally on earth?
Almost every element from hydrogen to uranium (going from smallest to biggest) is found naturally on Earth. Technitium is not found naturally on Earth, it is the exception. The trans-uranic elements are also not found naturally on Earth.
How does uranium get in to the environment?
1. Uranium exist naturally in rocks, soils, air and waters. 2. Man made contamination is from plants and mines leakages.
How do they make americium?
Americium is an artificial element (only extremely traces exist naturally on the earth); it is obtained by nuclear reactions (from uranium or plutonium) and a very long and difficult process of separation.

What is the heaviest element known to exist naturally on earth in quantities detectable by purely chemical test methods?
Now californium is considered as the heaviest naturally occurring chemical element.
Does uranium exist in a stable non-radioactive form?
All the isotopes of uranium are radioactive and unstable.
