Radium is a highly radioactive element and can be extremely dangerous. However, it was once used in many everyday products, including wristwatches and toothpaste, and thought to have curative ...
What is the importance of radium? Answer. Wiki User 04/02/2010. In the past radium was used for radiotherapy of some cancers or as a component of luminescent paintings. Now radium has very limited ...
Why is radium so important? Any list that rated the atomic elements in the order of their importance would place radium near the top. Actually there are two very different reasons for its outstanding importance. One is the unique role it played in the history of science. The other is its dramatic usefulness to mankind.
Because of its history, radium is a very interesting and important element. But radium and its compounds have relatively few uses. In fact, no more than about two kilograms (five pounds) of radium is made each year. The small amount of radium that is available is used for medical purposes.
By the Fifth Dynasty in the 25th and 24th centuries BC, he had become one of the most important gods in ancient Egyptian religion, identified primarily with the noon sun. Ra was believed to rule in all parts of the created world: the sky, the Earth, and the underworld. He was the god of the sun, order, kings, and the sky.
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 a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra 3 N 2).
The significance was that radium was many orders of magnitude more intense as a source of alpha particles than the previously available sources, such as uranium salts. For example, the Rutherford-Marsden discovery of the atomic nucleus would have been impossible without radium.
Although the benefits of radium fall far short of what it was once believed it could do, with careful handling radium still proves useful in medical treatment and scientific research. In addition, the story of its discovery is inspiring and laid the groundwork for many other important advances in science ...
Today it isn’t used for much, other than cancer treatment, but when radium was newly discovered, it was commercialized to a great extent and put in many things.. It was marketed as a miraculous panacea, and accordingly was added lots of things, something that in retrospect was an alarming practice.
