i think it's because of this fluro chemical.

metal

Abundance of radium in the earth crust: 9.10-10 mg/kg

Abundance of radium in the sea water: 8,9.10-14 mg/L

PORT RADIUM

Polonium and radium's affect on our lives today are for example the meters on our cars, they glow because of the radium and also some wristwatches the light you get when you press the button on the side. Radium was discovered by a woman named Marie Cuire, she's married, but she obviously died because of too much radium.

Radium was discovered by Marie Curie, Pierre Curie and Gustave Bemont in 1898.

Polonium and was discovered in 1898 by Pierre Curie and Marie Curie.

Marie Curie also discovered polonium. Her husband Pierre helped in the investigation also. She started off by studying a variety of chemical compounds that contained uranium. She discovered that the strength of the rays that came out depended only on the amount of uranium in the compound. It had nothing to do with whether the material was solid or powdered, dry or wet, pure or combined with other chemical elements. If you had a certain amount of uranium a certain number of uranium atoms-then you got a certain intensity of radiation. Nothing else made a difference.

The Nobel Prize in Physics 1903 was divided, one half awarded to Antoine Henri Becquerel "in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity",the other half jointly to Pierre Curie and Marie Curie.

The short version is that, just as certain numbers of electrons give inert elements and certain other numbers give highly reactive elements, the stability of a nucleus is dependent on the number of neutrons and protons. Some isotopes of gold contain the proper numbers of nucleons to be stable; no isotopes of radium do, so radium is radioactive.

Buy a bunch of old clocks and watches that have luminous numbers and the pointers that glow also. That is radium. Some of it was painted on by hand. In order to keep their paint brush sharp the worker would put it in their mouth and pull it out. Sucking on radium has bad health effects. The buildings where this was done are still very contaminated and the painters died of radium poisoning. Not sure if you can legally own it. Transporting it may be a crime. Possessing it is very dangerous and not recommended at all. Madam Currie, who discovered it, died from it. All isotopes should be kept in a secure and shielded place. Handling it only when necessary and with full protection from it.

Today radium has only limited applications in research laboratories, for example for the preparation of radon standard solutions, in neutron sources of the type Ra-Be, etc.

Possible use in radiotherapy of some cancers.

Radium was used in the past for luminescent painting of watches and other instruments, was used rarely in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.

The short form electron configuration of radium is: [Rn]7s2.

Henri Becquerel discovered the radioactivity of uranium in 1896.

Polonium and radium were discovered in 1898 by Marie and Pierre Curie.

Up to 700 0C radium is a solid metal.

Rutherfordium is radioactive and a solid, liquid, and gas;)

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.

The valence of radium is 2+.

The first name was radium; some isotopes had in the past other names.

Pierre Curie, Marie Curie and Henri Becquerel.
