Radium is nearly pure white. When it is exposed to air, though, it immediately oxidizes, turning black. The heaviest of the alkaline earth metals, radium is a chemical element whose atoms - like those of the other alkaline earth metals - have two electrons in their outermost shell; this causes them to react readily and form numerous compounds. The luminescent quality in radium made it ideal for use in self-luminous paints for watches, instrument dials, clocks and the like. Unaware of the danger of the extreme radioactivity of the element, many watch-dial painters who shaped their paintbrushes by putting them between their lips, died from the extended exposure to the radium in the paint. With its hazards come benefits. Today, radium is used medically to treat some kinds of cancer. On this date in 1898, scientists Pierre and Marie Curie and Gustave Bemont discovered radium in pitchblende that came from the now Czech Republic.
Radium has probably a silvery metallic appearance.
when radium is exposed to air it turns black
In pure form it is white, but turns black when oxidised in the air.
Radium has a silvery metallic appearance; radium is luminescent (with a blue color).
Radium has a silvery metallic appearance; radium is luminescent (with a blue color).
A blue color, not so intense.
Yes. Radium is actually considered an alkaline earth metal. Its colour is nearly pure white, but when exposed to air, it turns black. Radium is also extremely radioactive. A link is provided to the Wikipedia article on radium.
Radium is a chemical element, not a compound.
Radium is not a common commercial product.
Radium chloride, RaCl2, was the first radium compound to be prepared in a pure state and was the basis of Marie Curie's original separation of radium from barium. The first preparation of radium metal was by the electrolysis of a solution of radium chloride using a mercury cathode.
The first name was radium; some isotopes had in the past other names.
