Radium
Radium is a chemical element with the atomic number 88 and the symbol Ra. It was discovered by Marie Curie and Pierre Curie in 1898 in uranium ore.
404 Questions
What nationality was the scientist who discovered radium?
Radium was first isolated in 1898 by Marie Skłodowska-Curie, her husband Pierre Curie, and Gustave Bémont. Marie Curie was born in Poland in 1867. She later became a French citizen. The radioactive element polonium (that she isolated earlier in 1898) is named for her native Poland.
One of the ideas it generated was to use radioactive elements to kill cancers and other undesirable tissue growths.
Where can you buy used medical equipment?

What is the cost of radium per 100g?
There is no standard market price per gram of radium at this time, all extractions are done by special order so prices would have to be individually negotiated. The most recent price per gram that I could locate was roughly $10,000 per gram. This would make your 100 grams cost roughly $1,000,000.
If radium and polonium was not discovered how would it affect us today?
Radium and polonium have many applications but they are not so important to affect us today.
Can you apply cold compresses to a radium burn?
Do not apply cold compresses to a radium burn. Seek medical attention immediately as radium burns can be serious and require specialized care. Cooling the affected area with water may be recommended until medical help is obtained.
What fraction of radium will last for 3240 years?
Radium has a half life of 1601 years. So 24.6% will remain after 3240 years.
How many protons are in an atom represented by 220 88 Ra?
The 220 is the atomic MASS, which is the number of protons plus the number of neutrons. 88 is the atomic NUMBER, which is the number of protons only. The "Ra' is the abbreviation for radium, one of the first-detected radioactive elements.
radium was founded by Marie curie and Pierre curie.it was termed rad which means first in polonium since it was the first radioactive substance to be discovered
This is a sad tale. The Radium Girls, five employees of the United States Radium Corporation, were women who worked with radium paints and sued the company because they became ill. Grace Fryer, Edna Hussman, Katherine Schaub, and sisters Quinta McDonald and Albina Larice were the plaintiffs in this famous lawsuit. All of them ended up dying within a few years of the litigation, and all their deaths were a direct result of radiation poisoning due to radium. These women (and many others) applied the radium-containing coatings to the dials of clocks and aircraft instruments so they would "glow in the dark" and could be seen without light (owing to the radioluminescent property of the paints). Radioluminescent paint contains a radioactive isotope (in this case radium-226) combined with a radioluminescent substance (copper-doped zinc sulfide paint). To paint on the radium compounds, these women would put the tips of the brushes (that had the radium paint on them) on their lips to give the bristles an optimum shape. This quite naturally left a bit of the highly radioactive material on their lips. Over a period of time, these women got a large dose of radiation, and they (and a large number of others who worked with them as well as others who worked to refine the radium and make the paints) developed serious (and sometimes fatal) medical maladies. They had been told the paint was harmless. A link to the Wikipedia article on the Radium Girls is provided. A link is also provided to the imdb post on the 1987 documentary film "Radium City" which covers the particulars. This film is worth watching. It's accurate, gritty.
Probably not, but the radioactive isotope Plutonium-238 is used in nuclear-powered pacemakers.
When did we stop using radium?
We have never stopped using radium. Many "trivial" uses and certain "inappropriate" medical uses were stopped decades ago. While many valid uses of radium have have stopped because better or safer materials (e.g. tritium, cobalt-60, caesium-137, promethium-147) have been found for those purposes, radium still has certain specialized medical and industrial uses where nothing else can yet take its place.
Who discovered radium and when?
Radium was discovered in 1889 by French chemesists Marie Sktowska-Curie and her husband. Some common uses for radium is in self luminous paints, "glow in the dark" lights in most watches, and medical use. It is not very safe for medical use and is therefore used mostly by quacks because of extremely dangerously high level of radiation.
When Radium Bonds With Oxygen Does It Form A Covalent Or Ionic Bond?
Radium oxide has never been characterised. As radium is group 2 metal with chemistry like barium, radium oxide is expected to be ionic.
What type of radiation does radium give off?
Radium emits alpha, beta, and gamma radiation.
Alpha radiation is fully ionized helium nuclei. Beta radiation is high energy electrons. Gamma radiation is very high energy electromagnetic radiation. All of these can do significant damage to living things.
What can you combine radium with?
Radium is most commonly combined with beryllium, to create a neutron source for various applications such as in neutron radiography and in some types of cancer treatment. Combining radium with other elements can be dangerous due to its highly radioactive nature.
