Radium is a solid alkaline earth metal.
Radium is a solid in standard temperature and pressure.
At room temperature and pressure radium is a solid metal.
At room temperature and pressure radium is a solid metal.
Radium is solid at room temperature, but it can be turned into a liquid at 700 0C.
The most common state of matter for radium is solid, specifically a metallic solid. Radium is a radioactive element that is typically found in the solid form due to its high atomic number and density.

Radium chloride is a compound made of radium and chlorine. It is a radioactive substance known for its luminescent properties. Due to its high radioactivity, it is used in scientific research and medical applications, but must be handled with extreme caution.
Radium (Ra) has an atomic number of 88, which means it has 88 protons in its nucleus. In its neutral state, it also has 88 electrons. Radium is an alkaline earth metal and is known for its radioactivity. Its most stable isotope is radium-226.
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 has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this Skeleton equation: Ra + O2 --> RaO.... Balanced equation 2Ra + O2---> 2RaO
