Radium is a chemical element; a compound has a minimum of two chemical elements.
Radium is a chemical element, not a compound.
Radium and zinc do not have a strong attraction for each other, so they do not readily combine to form a compound. It is unlikely for these two elements to form a stable chemical bond due to differences in their chemical properties.
Radium is a natural chemical element, solid, alkaline earth metal.
The formula of radium perchlorate is Ra(ClO4)2, but this compound is not still prepared.
Radium is a chemical element Polonium is a chemical element Both were discovered by Marie Curie
Radium is a chemical element, not a compound.
The compound RaO is called radium oxide. It is a chemical compound composed of radium and oxygen atoms. Radium oxide is a highly reactive and radioactive compound.
Each chemical element, each chemical compound is unique and interesting. See the link.
Radium is a chemical element, not a mixture.
The chemical formula for radium oxide is RaO. Radium is a group 2 element, so it typically forms a +2 oxidation state. This compound is an ionic compound where radium is in the cation form and oxygen is in the anion form.
Radium is a radio active element which always undergoes nuclear fission and desentegration, and releases energy in the form of radiation. It is an element. There is no compound in it. It contains atoms of radium.
Radium is a divalent chemical element; the cation is Ra2+.
