Radium

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.

The number of electrons in a radium atom is usually 88. If it goes though bonding however, it will tend to lose those two outer electrons, and become a radium ion. If it bonds with oxygen, which has 6 outer electrons, it will lose the two outer electrons it has to become a radium ion with a full outer level of 86 electrons, and oxygen will get a complete outer level of 8 electrons. Radium will become Ra2+, a typical radium ion, also known as Radium 86, as it loses 2 electrons.

Radium lose two electrons, the cation is Ra2+.

Radium is a chemical element with the symbol Ra and atomic number 88. It is a radioactive metal that is part of the alkaline earth metals group. It is formed through the decay of uranium and thorium in the Earth's crust.

Radium is an element, with atomic number 88. The element radium is a radioactive alkaline earth metal that is the decay product of thorium, element number 90. (Thorium is, itself, the radioactive daughter of uranium.) Radium (226Ra, the isotope that is the result of the alpha decay of thorium) has a half-life of 1602 years, and the element acts chemically like the other +2 elements in group 2 of the periodic table. It is highly radioactive and dangerous. (Links are provided to the Wikipedia article on radium and also to a related question.)

The radium nitride (Ra3N2) has a black color.

Atomic number of uranium: 92 (the same for all the isotopes) Atomic number of an element = number of protons = number of electrons Atomic mass of the isotopes of uranium: 234, 235, 236, 238, 239, 240, ...., etc. Atomoc mass - Atomic number = Number of neutrons

Radium is a solid, radioactive, alkaline earth metal.

Radium is a highly reactive element, and it readily reacts with elements such as oxygen, water, nitrogen, and halogens. Its reactivity is due to its position in the periodic table as an alkaline earth metal, leading to the formation of various compounds.

Radium is a radioactive element that was discovered by Marie Curie and her husband, Pierre Curie. It was used in the past for medical treatments and in luminescent paints. Polonium is another radioactive element discovered by Marie Curie, named in honor of her home country of Poland. It is highly toxic and was used as a heat source in early space missions.

Polonium is a rare radioactive element with symbol Po and atomic number 84. It was discovered by Marie Curie and her husband Pierre Curie in 1898. Radium is another radioactive element with symbol Ra and atomic number 88. It is also discovered by Marie Curie, and both polonium and radium are highly toxic and carcinogenic.

Marie Curie and her husband Pierre Curie were scientists who worked with radium in France. They were pioneers in the field of radioactivity and won the Nobel Prize for Physics in 1903 for their research on the subject.

Radon is the noble gas generated when radium decays through radioactivity. It is colorless, odorless, and tasteless, making it difficult to detect without proper equipment. Radon is radioactive and can accumulate in enclosed spaces, posing health risks if inhaled in large amounts.
