Radium

In English, radium is pronounced as "ray-dee-uhm."

Alcohol is a molecular compound made up of different elements such as carbon, hydrogen, and oxygen. Therefore, it does not have a single atomic number or atomic mass. The atomic number and atomic mass of the individual elements in alcohol (e.g., carbon, hydrogen, and oxygen) would need to be considered instead.

Combining sulfur and radium would likely result in the formation of radium sulfide. Radium sulfide is a radioactive compound that emits harmful radiation. Handling and storing this compound would require specialized precautions due to its radioactivity.

Radium itself does not produce a colored flame when burned. It is a radioactive element that emits alpha, beta, and gamma rays, but these emissions are not visible as colors in a flame. Radium is more known for its characteristic glow, called luminescence, in the dark due to its radioactivity.

In the past radium was used for the radiotherapy of some cancers or as a component of luminescent paintings. Now radium has very limited uses: source of neutrons as Ra-Be, source of radon, research laboratories.

Marie Skłodowska Curie and her husband Pierre discovered the elements polonium and radium in 1898, and named polonium for her native country Poland.

Radium is a chemical element, not a compound.

Radium is a radioactive element that is never found in its pure form in nature due to its highly reactive and unstable nature. It is typically found in minerals like uranium and thorium ores, and extracting pure radium requires complex and hazardous procedures.

Polonium and radium are both radioactive elements that cannot be photographed because they are not visible to the naked eye and require specialized equipment to detect. They emit radiation that can be harmful to living organisms.

Radium is naturally occurring and present in the Earth's crust. It is a decay product of uranium and thorium. Despite being radioactive, traces of radium remain in the environment due to its long half-life.

If there was no more radium, it would impact industries that rely on its radioactive properties for medical treatments, industrial radiography, and scientific research. Some existing applications may need to find alternative sources or technologies, which could lead to adjustments in processes and potential innovation in these sectors. Additionally, it would affect historical artifacts and devices that contain radium, as well as the study of radioactivity and its effects on health and the environment.

metal

The abundance of radium in the sea waters is 8,9.10-14 mg/L.

Calcium and radium are in the same group of the periodic table of Mendeleev (group 2, alkaline earth metals); consequently calcium and radium has similar chemical properties and can be interchangeable in some situations.

In Paris, France, in 1898.

The announcement was made on December 26, 1898. It was isolated from the residues of the uranium ore pitchblende by Marie and Pierre Curie and Gustave Bémont. Pierre died in 1906, and Marie Sklodowska Curie (1867-1934) received the Nobel prize for Chemistry in 1911.

i think it's because of this fluro chemical.

Today radium is not so important for practical applications:

- radium-beryllium neutron sources

- preparation of radon standard solutions

- possible use in radiotherapy for some cancers

Radium has 88 electrons.

The number of neutrons is different for each isotope:

Number of neutrons = Atomic mass of an isotope - 88

The New York Times article questioning the price of radium -- at US$120,000 per gram -- could be interpreted to mean that these two minerals may be competitors in the price wars. (Below.)

A diamond weighing a gram would weigh about five carats. If the stone were of a high colour, high clarity, and superior cut, it might cost about the same amount of money.

A fancy intense vivid stone with the same description would probably cost more.

1. Radium has 45 isotopes and nuclear isomers.

2. Radium has no known today allotropes.

Now radium hasn't practical applications. Uranium has many applications as nuclear fuel and also in nuclear weapons and strong tank armors.

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.

Radium was first used in medicine to treat various medical conditions, such as arthritis and cancer, due to its ability to destroy diseased tissue. It was also used as a luminous paint in products like watch dials and aircraft instruments, as well as in the production of glow-in-the-dark products.

No, glowsticks do not contain radium. Glowsticks work by a chemical reaction that produces light through chemiluminescence, typically utilizing a mixture of hydrogen peroxide and a phenyl oxalate ester. Radium is a radioactive element that is not used in glowsticks for safety reasons.
