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 atomic number 88 stablest isotope 226 melting point about 700 °c (1,300 °f) boiling point not well. Radium is radioactive, so its chemical properties are difficult to study the alkaline-earth metals have very similar chemical and physical properties they can be studied as a whole, rather than element-by-element, due to this similarity. Facts date of discovery: 1898 discoverer: pierre and marie curie name origin: from the latin word radius (ray) uses: treating cancer obtained from: uranium ores related links. Chemical element written by: robert c brasted martin klaproth in 1789, and polonium and radium by the french scientists pierre and marie curie in 1898.
Radium's most stable isotope, radium-226, has a half-life of about 1600 years it decays into radon -222 through alpha decay or into lead -212 by ejecting a carbon -14 nucleus the curie, a unit used to describe the activity of a radioactive substance, is based on radium-226. Radium is the sixth element of the second column in the periodic table it is the heaviest of the alkaline earth metals radium atoms have 88 electrons and 88 protons with 2 valence electrons in the outer shell. It is an alkaline-earth metal in its chemical properties it closely resembles barium, the element above it in group 2 of the periodic table when radium is exposed to air, a black coating of nitride rapidly forms.

Discover plenty of periodic table facts on the chemical and physical properties of the element radium radium facts search the radium facts chemical & physical. Radium: description your user agent does not support the html5 audio element pure metallic radium is brilliant white when freshly prepared, but blackens on exposure to air, probably due to formation of the nitride.
Element bingo element word search in addition to the information contained within the periodic table of elements, the following articles may be helpful if you are writing a report about an element or if you are making a model of an atom. Facts about radium by rachel ross, which then into several other unstable elements before finally ending in the element lead there are several known isotopes of radium, but due to the rapid. For this element, for actinium, and for polonium, but for none of the others, are the criteria of unique spectrum and chemical character, as found for radium, to be (continued on page 77) prof s. Radium is not a primordial element, but is a trace element that occurs from the decay of other heavier elements there are no large deposits of radium due to the extremely short half-life of the element and all its isotopes. A radioactive element is one with an unstable nucleus, which radiates alpha, beta or gamma radiation and gets converted to a stable element this article has a comprehensive list of radioactive elements and their properties.

History (poland, native country of mme curie) polonium, also called radium f, was the first element discovered by mme curie in 1898 while seeking the cause of radioactivity of pitchblend from joachimsthal, bohemia. Chemical properties of radium are its high reactivity and that it continuously breaks down and changes into other elements most radium isotopes, or atoms that have a different number of neutrons than the normal radium atom, are unstable and radioactive the half-life of radium's most stable isotope.
Radium is a radioactive chemical element which has the symbol ra and atomic number 88 its appearance is almost pure white, but it readily oxidizes on exposure to air, turning black radium is an alkaline earth metal that is found in trace amounts in uranium ores.
