Any of a variety of elements might do for this, including thorium and uranium, but even potassium has an important radioactive isotope in it.
thorite
Thorite
If a mineral contains more than one element it is called a
Francium is a radioactive, very rare, natural chemical element.
uranium is probably the source for radioactive isotopes derived from nuclear reactors
Astatine is not a mineral but a chemical element. Astatine can be obtained as a pure element but in extremely small quantities.
A silicate is a mineral which contains the element silica.
For example graphite.
Feldspar
An example of a mineral that contains more than one element is feldspar, which is a group of rock-forming tectosilicate minerals. Feldspar typically contains a combination of elements such as aluminum, silicon, oxygen, potassium, calcium, and sodium in varying proportions.
A mineral may consist of a single element, but most often contains two or more elements. Gold--single element mineral. Calcite--made up of calcium, carbon and oxygen.
No, iron ore and uranium ore are two different types of ores. Iron ore is a mineral that is a source of iron while uranium ore is a mineral that contains uranium, a radioactive element used for nuclear energy production.
