Radium was once used for a treatment for cancer, as it is very radioactive, but is now being replaced by other elements. It was also used in glow-in-the-dark paints and watches, but that was stopped after the workers who made the paint a and watches kept dying.
Polonium applications: - neutron source (polonium-beryllium source) - in devices for the elimination of the static electricity - in devices for the elimination of the dust - initiator in nuclear weapons - isotopic heat source Radium has not today practical applications.
Hydrogen chloride is used in the production of PVC, a widely used plastic material. It is also used as a cleaning agent in various industries. Additionally, hydrogen chloride is used in the production of chemicals such as hydrochloric acid, which is used in various industrial processes.
Alum is used in vaccines as an adjuvant. Alum is commonly used as a coagulant in water treatment. And its used for domestics water.
Iron is used in the production of steel. Copper is used in electrical wiring. Gold is used in jewelry and electronic components. Diamond is used in cutting and drilling tools. Silver is used in photography and currency.
Borax decahydrate is commonly used as a cleaning agent and laundry booster. It can also be used as a pesticide, fungicide, and herbicide. Additionally, borax decahydrate is used in various industrial processes such as metal refining and textile manufacturing.

Both. During decay it ceases to be radium.
Because all scientists want to increase the knowledge of humanity.
Hi How to Make a Crane game is get The parts @ www.Cranegames.com :-) Hope this helps
raduim ??? chech the periodic table
Radium element is in the s block. It has 88 protons in a single atom.
According to the Wikipedia article on radium, the melting point of radium is 700 degrees Celsius.
This element was first isolated in France, near or in Paris, from ore brought from some other place.
Electron configuration of radium:Ra: [Rn]7s2Ra(2+): 1s2.2s2.2p6.3s2.3p6.3d10.4s2.4p6.4d1o.4f14.5s2.5p6.5d10.6s2.6p6.
in 1900 it was called raduim emanation by Friedrich Ernst Dorn. and in 1910 it was called niton by Robert Whylaw-Gray. in 1923 is was finally called radon by the International Committee for Chemical Elements.
Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
