Radium is a chemical radioactive element which is represented by the symbol Ra. It has an atomic number of 88 in the periodic table. It is commonly used for research purposes, and it occurs naturally in the form of Radium 226 or Radium 228.

Radium is produced by the decay of the uranium and thorium series. It has a half life of 1,600 years. It emits alpha particles when it is transformed to radon, due to which it has a characteristic gleam. Due to this reason, in the past, radium was mixed with special paints to make watch and clock dials and watch faces glow in the dark.

This radioactive element is highly used as a source of neutrons. In addition, the use of radium in therapies like the 'Radium Therapy' is also known.
