Radium, a highly radioactive alkaline earth metal, reacts with water to form radium hydroxide and hydrogen gas. The reaction is exothermic, meaning it releases heat, and can be vigorous, especially with steam. Due to its radioactivity and reactivity, radium is handled with extreme caution in laboratory settings.

Radium was discovered by Marie Sklodowska Curie, a Polish chemist, and Pierre Curie, a French chemist, in 1898. Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it. She reasoned that pitchblende must contain at least one other radioactive element. Curie needed to refine several tons of pitchblende in order to obtain tiny amounts of radium and polonium, another radioactive element discovered by Curie. One ton of uranium ore contains only about 0.14 grams of radium. Today, radium can be obtained as a byproduct of refining uranium and is usually sold as radium chloride (RaCl2) or radium bromide (RaBr2) and not as a pure material.

Yes, radium can be present in small amounts in tobacco plants, which can transfer into cigarettes. However, the levels are typically very low and the main health risks associated with smoking come from other chemicals and compounds in cigarette smoke rather than radium.

Radium dust is a radioactive material that emits harmful radiation particles in the form of alpha, beta, and gamma rays. It is often produced as a byproduct of radium decay and poses serious health risks if inhaled or ingested, as it can accumulate in the body and damage cells, potentially leading to cancer or other health issues. Proper handling and disposal of radium dust is essential to prevent exposure and contamination.

The name radium is derived from the Latin language word radius (= radiation).

Polonium was discovered by Marie Curie and Pierre Curie in 1898.

Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898.

Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.

pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.

Since Radium is in the alkaline earth metal group, and we know that as you move down the group, it gets more reactive. So, since Radium is the last element of the group, another property of Radium is that it is highly reactive in nature.

It was featured in Guitar Hero II and released as a single in 2007. An album version was recorded for an album released in 2011 by Count Zero called Never Be Yourself.

No, radium does not glow in the dark. If it did, then the whole world would be glowing in the dark. Rocks, soil, plants, and any living thing contains some radioactive material.

The myth can be traced back to the "radium craze" of the early 20th century, when radium was just about added to everything. When the radium was added to paint, it became luminous.

This was the origin of the "radium glow". In fact, it wasn't the radium glowing, but it was reacting with the copper and zinc in the paint, causing it to become luminous, in a phenomenon called "radio-luminescence".

Radium was first isolated in 1898 by Marie Skłodowska-Curie, her husband Pierre Curie, and Gustave Bémont. Marie Curie was born in Poland in 1867. She later became a French citizen. The radioactive element polonium (that she isolated earlier in 1898) is named for her native Poland.

One of the ideas it generated was to use radioactive elements to kill cancers and other undesirable tissue growths.
