About 700 deg C.
The relationship between radium and its ionization energy is that radium has a high ionization energy. This means that it requires a lot of energy to remove an electron from a radium atom.
Igneous rocks like granite and basalt have high melting points and can withstand high temperatures before melting. Granite typically melts at around 1200-1300°C, while basalt melts at about 1000-1200°C.
Radium will react with oxygen to form radium oxide (RaO) or radium peroxide (RaO2), depending on the conditions. These compounds are highly unstable and radioactive. Due to the high reactivity of radium, such reactions should be avoided as they can lead to hazardous situations.
One metal that melts easily under high temperatures is mercury.
Radium is expensive due to its rarity and high cost of extraction. It is a radioactive element that occurs in very small amounts in the Earth's crust. The complex process of extracting and purifying radium further contributes to its high price.
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 forms an ionic compound with oxygen known as radium oxide (RaO). In this compound, radium, a metal, donates electrons to oxygen, a nonmetal, resulting in the formation of an ionic bond between them. Radium oxide is a solid compound with high ionic character due to the large difference in electronegativity between radium and oxygen.
Radium hydroxide is a strong alkaline compound, so it would have a high pH value. However, the exact pH would depend on the concentration of the radium hydroxide solution.
It is illegal to purchase or sell radium without the appropriate licenses due to its high radioactivity. Handling radium without proper training and safety measures can be extremely hazardous to health and the environment.
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.
Extremely expensive; radium is not a common commercial product. Radium can be delivered only to specialized research institutes.
It is resistant to sulfates. It can withstand high temperatures. (It melts at around 3000 F.) It is resistant to sulfates. It can withstand high temperatures. (It melts at around 3000 F.)
