What do you know about the element radium?

radium (Ra), radioactive chemical element, the heaviest of the alkaline-earth metals of Group 2 (IIa) of the periodic table. Radium is a silvery white metal that does not occur free in nature.

Is radium flammable yes or no?

Radium and its salts exhibit luminescence and impart a carmine color to flame. Radium emits alpha, beta, and gamma rays. It produces neutrons when mixed with beryllium. A single gram of Ra-226 decays at the rate of 3.7×1010 disintegrations per second.

How was radium named?

They finally isolated radium in 1902 in its pure metal form. Radium was named for the Latin for a ray and proved to be the most radioactive natural substance ever discovered.

What Colour does radium Glow?

green glow
Discovered by Marie Curie in the late 1800’s, radium was used by the US Radium Corporation in the early 1900’s to produce luminous paint by mixing it with zinc sulfide. The resultant mixture gave off a faint green glow, and was used to paint everything from watch faces to gun sights.
