Radium

In the periodic table, elements are organized into groups that have similar chemical properties. Group 2 elements, also known as the alkaline earth metals, share characteristics such as forming 2+ cations and reacting with water to produce alkaline solutions.

Radium emits harmful radiation in the form of alpha, beta, and gamma rays. Lead is a dense material that effectively blocks these types of radiation, making it ideal for containing and shielding radium to prevent exposure to harmful radiation.

Absolutely not. Radium is a highly radioactive alkali earth metal, and, though some of the elements from this chemical group are critical for life (if you don't have them you die), this one is to be avoided if it is at all possible. Zero radium is a good amount to have in your body any time. All the time, too.

Neutron sources use radium because it emits alpha particles, which can interact with beryllium to produce neutrons through the (alpha, n) reaction. This process allows for a reliable and efficient way to generate neutrons for various applications, such as scientific research, industrial testing, and medical diagnostics.

The chemical symbol of radium is Ra.

In the past radium was used for 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.

There aren't any "deposits" of radium compounds, but there are traces of it in a lot places where traces (or more) of uranium are found. The tiny bit of this element that occurs naturally is widely distributed. With a great deal of effort, it can be accumulated from the refining of carnotite, an ore of uranium. Radium is (highly) radioactive, and it is a daughter of the radioactive decay of thorium, which is, in turn, a radioactive daughter of uranium decay. The uranium and thorium in this decay chain are long lived, and radium is relatively short-lived. This translates into the idea that only trace amounts of it exist naturally. The chemistry of radium was known largely from working with only trace amounts. Additional information was gleaned from the study of larger quantities following its separation from carnotite, a uranium ore. A link to the Wikipedia article on radium is provided.

Radium typically has 138 neutrons. This is derived by subtracting the atomic number (88) from the atomic mass (226) of radium.

Yes, radium is a highly ductile metal. It can be easily bent and shaped without breaking. However, due to its radioactive properties, handling radium poses health risks and precautions should be taken.

There are 88 protons in a radium atom.

The density of radium at about room temperature is 5.5  g·cm−3. That's 5.5 grams per cubic centimeter, or 5.5 grams per milliliter. A link to the Wikipedia article on radium is provided.

thank you.....

please give me the right formula for dish wash

i want to now how many type chemical for dish washer formula

Radium is a highly reactive alkaline earth metal that is chemically similar to calcium and barium. It readily forms salts and compounds with other elements, and it is radioactive, emitting alpha, beta, and gamma radiation. Radium compounds are toxic and pose a health hazard due to their radioactivity.

Radium is a highly radioactive alkali earth metal, and it can be found in trace amounts in some water sources and in some soil or rock samples. That means this stuff isn't found in the atmosphere. (It may be in some dust, but not likely.) But it will be found in some places in the lithosphere (the ground or the earth) or the hydrosphere (the water). Radium is associated with the radioactive decay of uranium, so where traces or deposits of uranium ore are found, this stuff will be around. A link to the Wikipedia article on radium is provided.

Radon, a radioactive inert gas, will, when superheated, begin thermionic emission. Let's put some in a container we can see through (with nothing else to interfere) and heat it up. Ready? Let's do it. Electrons most loosely bound to the radon nucleus will move to the next higher available Fermi energy level (meaning the atom will ionize), and then the electrons will fall back to their original energy levels with the emission of a photon. The radon will be glowing - emitting light. The phenomenon will be repeated; more and more atoms of radon will become involved in the process. At first the light will be in the infrared spectrum and we will not be able to see it unaided. At higher heats, electrons are driven to higher and higher energy levels, and when they "fall back" into their orbitals, the will emit shorter and shorter wavelengths (higher and higher frequencies) of light in making the transition. Some reds, oranges, yellows and other colors on up the frequency spectrum will be given off by the glowing gas, but not necessarly all the colors. Radon is an unstable (radioactive) inert gas. And it has a short half-life. Let's assume that no radioactive decay occurred during our little experiment. We wouldn't want to have to deal with any of the radioactive daughters of radon that might appear and "mess up" our light show. If the question spoke to the shortening of the half-life of radon by superheating it, that is, if you want to make radon undergo radioactive decay faster by superheating it, set that notion aside. You can't affect its rate of decay by superheating radon. Oddly, almost all isotopes of all elements show a uniform resistance to having their half-lives changed by superheating them. We find little to no evidence of changes in half-lives of radioisotopes in stars, which are massive spheres of plasma that are hot almost beyond imagining.

No, radium is not magnetic. Radium is a radioactive metallic element that emits highly energetic alpha, beta, and gamma particles as it decays. Magnetism is a property associated with the alignment of magnetic moments in a material, which radium does not exhibit.

1. Radium has 88 protons.

2. Radium has not... americium !

Radium-223 chloride (Xofigo) is a radioactive drug used to treat prostate cancer that has spread to the bones. It works by delivering targeted radiation directly to bone metastases, which helps reduce pain and improve overall survival in patients with advanced prostate cancer. Radium-223 can help improve quality of life by reducing bone pain and delaying the progression of the disease.

1. Marie Curie, Pierre Curie and Gustave Bemont discovered radium in 1898.

2. Maria and Pierre Curie isolated radium chloride in Paris in 1902.

3. Marie Curie, Pierre Curie and Andre Louis Debierne prepared radium as a pure metal in 1910.

In July 1898 Pierre and Marie Currie published a paper revealing their discovery of "polonium", In December 1898 announced a second new element, "radium"
