  1. Radium By: Arvin Chen G9 Pearl

  2. About Radium Radium is a chemical element with an atomic number of 88. Radium is an almost pure-white metal from Earth that is an alkaline, but it easily oxidizes on exposure to air, becoming black in color. Isotopes of Radium are highly radioactive which is the reason why it is luminescent, glowing a faint blue. Pure radium is a white, silvery, solid metal, melting at 700 °C and boiling at 1737 °C. Radium has a density of 5.5 g/cm3. Radium is the heaviest known alkaline earth metal. When exposed to air, radium reacts violently with it, forming radium nitride, which causes blackening of this white metal. Radium reacts violently with water to form radium hydroxide

  3. Uses Radium had been used for a variety of luminescent paint, recreational use, medical use, and research Radium had been used to make self-luminous paints for watches, aircraft instrument dials and other instrumentation until it has largely been replaced by cobalt-60, a less dangerous radioactive source. Radium is used to produce radon, a radioactive gas used to treat some types of cancer. A single gram of radium-226 will produce 0.000l milliliters of radon a day. In 1909, the famous Rutherford experiment used radium as an alpha source to probe the atomic structure of gold. This experiment led to the Rutherford model of the atom and revolutionized the field of nuclear physics

  4. Discovery Radium was discovered by Marie Sklodowska Curie, a Polish chemist, and Pierre Curie, a French chemist in 1898 in the form of Radium Chloride. Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated. She reasoned that pitchblende must contain at least one other radioactive element. They published the discovery at the French Academy of Sciences In nature, radium is found in uranium ores in small amounts. Radium is not necessary for living organisms, and prevention of health effects are likely when it is incorporated into biochemical processes because of its radioactivity and chemical reactivity

  5. Major Producers and Importance of Radium Known major producers of radium today are Kazakhstan, Canada, and Australia. Radium was important and was used a lot in the past but now the importance of radium has very limited uses. Radium is now known for being used as research for neutrons. When Radium is mixed with beryllium, it is a neutron source. This type of neutron source were for a long time the main source for neutrons in research. Although there is no information about the population of the people living in the places of the major producers of radium, we can say that the population may have decreased a little due to people dying from high exposure of radiation from radioactive dumping until the producers found a way to prevent this rom happening and the people are safe.

  6. Advantages and disadvantages of Radium Advantages of radium are that, in the past, radium was used to produce radon, a radioactive gas that is used to treat some types f cancer, thus saving many people in the past. It is also used for luminescent painting on watches and aircraft so that the objects can glow in the dark and allow us to see. It famously used today as research for neutrons. Disadvantages of radium are that, radium is extremely reactive with air and water, which is why it is found in ores all of the time. Lots of people died in the past due to large exposure to radium. When during treatment, using a lot of radon is not good for the body, it can kill the person because of large amounts of radiation in the person. Due to radium being very reactive and highly radioactive, it can be most likely dangerous when touched.

  7. In the Future I would not think that scientists will think of any other uses for radium since of its high radioactivity. I think it will only be used for researching on neutrons. No scientists have said anything about using radium for anything else in the future due to the element being the heaviest known Earth metal and almost on the same chemical properties of Barium. Learning about this metal relates back to our chemistry class about learning the history and information about specific types of metals in the periodic table and learn more about them.
