Radium: Element Properties And Uses
Description
Radium is a rare, radioactive element noted for its distinct chemical and physical properties. Its production methods and frequent applications influence modern industry.
Introduction to the Element
Radium is an element that has attracted scientific attention since its discovery. It was originally isolated from uranium ores. It became known for its luminescence and high radioactivity. Its defined properties have led to extensive academic studies and practical applications in areas such as medicine and industrial manufacture.
Description of Chemical Properties
Radium exhibits high radioactivity and marked chemical reactivity. As a member of the alkaline earth metals, it shows characteristics common to elements like barium. However, its instability sets it apart.
It forms compounds such as radium chloride and radium sulphate. These compounds decay rapidly and emit alpha particles. This behaviour not only governs radium’s interactions with other substances but also determines the methods used for its handling and storage.

Common Uses
Radium has been applied in various practical contexts over the years. One well-documented use was in luminous paints applied to dials, aircraft instruments and exit signs.
In the medical sector, radium was utilised in radiotherapy to treat certain cancers. Its ability to emit strong radiation was applied according to strict safety protocols. Although many of these uses have been reassessed in line with modern safety standards, its historical application has left a lasting impact on consumer products and medical treatments.
Preparation Methods
Radium is extracted from uranium-bearing ores such as pitchblende. The process begins with the physical reduction of the ore. It is followed by a series of chemical treatments that aim to separate radium from other elements. Given that these procedures involve multiple purification steps, the resulting radium is produced with minimal impurities.
