What must occur before a radioactive atoms ceases to undergo further radioactive decay?
A stable, nonradioactive atom must be formed.
Electrons in uranium?
The most stable form of uranium (U-238) contains 92 electrons.
Uranium slowly decay or dissolve to form?
Uranium slowly decay to form the stable nucleus of Lead after a series of nuclear reactions.
Do you find radium in its pure form?
Radium exist in very small concentrations in uranium ores but not in a metallic, pure form.
What elements can uranium combine with to form a compound?
Uranium form chemical compounds with the majority of the other elements.

Uranium slowly decay or dissolve to form?
Uranium slowly decay to form the stable nucleus of Lead after a series of nuclear reactions.
Where can francium can be found on earth and in what form?
Francium exist in uranium and thorium ores; the chemical form is not known.
Do you find radium in its pure form?
Radium exist in very small concentrations in uranium ores but not in a metallic, pure form.
Is an atom of phosphorus stable?
No. Phosphorus is reactive with oxygen, so it does not exist in elemental form in nature.
Is plutonium found free or is it chemically combined in nature?
Plutonium exist in extremely low concentrations in uranium minerals; the chemical form is probably plutonium dioxide or a complex oxide with uranium.
Why noble gases exist either in atomic form or in molecular form?
They have completely filled valence electrons, hence are stable, chemically inert. So they exist as mono atomic species and not as molecules
Why does uranium not spotaneously combust in mines?
It is not in a concentrated form of metal, but is usually in the form of uranium oxide.
What ore is commonly used in nuclear power plants?
The primary uranium ore mineral is uraninite (UO2) or pitchblende (UO3, U2O5), commonly collectively refered to as U3O8(the most stable form). A range of other uranium minerals can be found in various deposits.
Is plutonium usually in a compound or pure form?
In nuclear weapons plutonium exist as metal or as an alloy Pu-Ga; in nuclear fuels plutonium is as dioxide (mixed with uranium dioxide) or carbide (also possible mixed with uranium carbides).
Can uranium and plutonium bond?
Uranium and plutonium can form alloys.
