The most stable isotope is radium-226, with a half-life of about 1600 years. But there are four naturally occurring isotopes, including Radium -223, Radium -224, Radium- 226, Radium- 228. IsotopesĪround 33 isotopes have been discovered with mass number ranging from Ra 202 to 234.

Exposure to higher levels of radium may result in health effects, such as teeth fracture, anemia and cataract. Radium levels in drinking water may be high when it is extracted from deep wells that are located near radioactive waste disposal sites. Its radiation can also kill healthy cells. But great care must be taken in using radium for this purpose. Killing cancer cells can help a patient recover from the disease.

This property is desirable in treating cancer. It gives off radiation which can kill living cells. Like radioactive elements radium is a dangerous substance to handle. Radium forms many insoluble salts, including sulfate, chromate, carbonate, iodate, and nitrate.
#RADIUM COLOR PORTABLE#

It is 6 th element in group 2 of periodic table. Melting point 700 C and boiling point 1140 C. Its atomic symbol Ra, atomic number 88, atomic weight 226, solid at room temperature. Radium is silvery, lustrous, soft and radioactive element.
#RADIUM COLOR SERIES#
Radium is a radioactive element of the alkaline earth series of metals. It was derived from Latin word radius which means rays. Radium originally found in pitchblende ore. This makes it the 84 thmost abundant element. Radium has an abundance in the Earth’s crust by weight about 1 part per trillion. Due to the high solubility of its compounds in water, radium is extracted by successive lixiviation of the referred ores. In nature, radium is found in uranium and thorium ores in trace amounts as small as a seventh of a gram per ton of uraninite. Today, radium can be obtained as a byproduct of refining uranium and is usually sold as radium chloride (RaCl 2) or radium bromide (RaBr 2) and not as a pure material. They isolated pure radium in 1911, via electrolysis of radium chloride. Radium was discovered in 1898 by Marie and Pierre Curie (a Polish and French chemist, respectively). It is a lustrous metal and is widely used in various industry. Radium is an alkaline earth metal and was discovered in 1898 by Marie and Pierre Curie.
