Uranium is found in many compounds, though not all these compounds are useful. Notably, however, a uranate is a particular oxide involving uranium in different oxidation states, and is often found in that state in other compounds, such as ammonium diuranate.
Uranium is found in the earth only in the form of compounds. Uranium is present in cca. 200 minerals.
Selenium is an element. Elements don't contain compounds.

1. Uranium contain atoms, not molecules. 2. Many chemical compounds contain in the molecule uranium: uranium dioxide, uranium tetrafluoride, uranyl nitrate, etc.
Uranium is a very reactive element and can form alloys or compounds with the majority of the elements of the priodic table of Mendeleev.
Uranium (as an element) has atoms, not molecules; uranium compounds are molecules.
Organic compounds always contain the element carbon.
Organic compounds contain the element CARBON (C).
All organic compounds must contain the element carbon.
Uranium is found in the earth only in the form of compounds. Uranium is present in cca. 200 minerals.
Uranium is a very reactive element and consequently react with many elements; examples: oxygen, chlorine, fluorine, sulphur, etc.
Xenon is an element and, being an element, it cannot contain any compounds - man-made or natural.
Selenium is an element. Elements don't contain compounds.
