A soft, shiny and silvery radioactive metal. Radium now has few uses, because it is so highly radioactive. Radium-223 issometimes used to treat prostate cancerthat has spread to the bones. Because bones contain
Ionizing radiation is given off by radioactive material, very high-voltage equipment, nuclear reactions and stars. It's both natural and man-made. A natural source of ionizing radiation is radon, a radioactive material found underground. X-rays are a good example of man-made ionizing radiation...
Radioactive materialcan be transported by truck, train, plane or ship. There are special regulations that help keep drivers, the public, and the environment safe. The packaging used to transport radioactive material is tested to make sure it will keep people safe if there is an accident. How...
Uranium is the best example of such an element and is the heaviest naturally occurring radioactive element. There are eight other naturally radioactive elements: polonium, astatine, radon, francium, radium, actinium, thorium and protactinium. All other man-made elements heavier than uranium are ...
Why does radioactive decay occur? Uranium-238 undergoes alpha decay and becomes What is the product of the alpha decay of cobalt-60? What happens when the nuclide astatine-218 undergoes alpha decay? What kind of decay is carbon-14 alpha decay?
Half-life is a time parameter that is used in radioactive decay. The half-life is a measurement of time where a decaying substance reaches half of its original amount. Half-life is used in exponential decay processes, which me...
Actinides:The actinides line the bottom row of the island and comprise elements 89,actinium(Ac), through 103,lawrencium(Lr). Of these elements, onlythorium(Th) anduranium(U) occur naturally on Earth in substantial amounts. All are radioactive. The actinides and the lanthanides together form...

The atomic mass of the element is determined by the combined masses of neutrons and protons. True or false? Explain. Why does chlorine have a higher electronegativity value than krypton? What determines whether an isotope is radioactive or not? What is the pri...
