Radium is not used as a component of luminescent paints from about 80 years !
Both radium and polonium are radioactive elements and are not stable.
Polonium and radium are continuously studied, but not so much.
Any link between Dalton and polonium&radium.
As radium is radioactive, radium chloride would also be radioactive. Any compounds make with any radioactive material are radioactive, and they cannot be "not" radioactive. Radioactive material doesn't really care if it is "alone" or in compound; it will be radioactive in any case.
1. Radium has 88 protons. 2. Radium has not... americium !
Of course, many scientists worked with radium and polonium.
Any link exist between X-rays and polonium&radium.
Hilter did not write any novels.
1. Radium has 45 isotopes and nuclear isomers. 2. Radium has no known today allotropes.
No, any link
yes there are.
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. Now radium hasn't any use at home and in the industry.
