An atom of plutonium contain protons, neutrons and electrons - not other elements.
Basically, all (or most) of the elements found in the periodic table, up to plutonium.
There are two elements that make up the compound NaBr, or sodium bromide. These two elements are sodium and bromine.
Basically, all (or most) of the elements found in the periodic table, up to plutonium.
Calcium (Ca) and Oxygen (O) are the two elements that make up calcium oxide.
There are many reactive elements. They show up more on the upper left of the Periodic Table. Some of these are plutonium, uranium, Mercury and lead.
Iron is, itself, and element. It is not a compound of two elements.
The two elements that are in KBr are Potassium and Bromine.
it is a mixture. there are more than two elements and substances that make it up.

A very small amount of plutonium is found in nature. The majority of it is produced artificially.The majority of plutonium is made in nuclear reactors:uranium-238 captures a neutron, becoming uranium-239uranium-239 undergoes beta decay, becoming neptunium-239 (halflife 23.5 minutes)neptunium-239 undergoes beta decay, becoming plutonium-239 (halflife 2.33 days)plutonium is then chemically separated from the remaining uranium, neptunium, etc.
two or more different elements
Iron and oxygen
