What’s true of a radioactive element? FEMALE STUDENT: It decays? It turns into other elements?Oh, so does that explain why it was missing in the periodic table? MALE PROFESSOR: Exactly. Because of its radioactive decay, element 43 doesn't last very long …and therefore… if it ever ...
4. Geothermal Energy:There is a tremendous amount of energy stored within the Earth that is not fossil fuels. It is known asGeothermal energy. Since the Earth was formed, there has been a constant decay of minerals that were part of the make-up. Many are radioactive in nature and release...
Which elements found in nature have mainly radioactive isotopes? What elements are radioactive and synthetic? What natural elements are poisonous? What is another name for the rare-earth elements? Which natural elements are used to keep the Earth clean?
Radioisotopes, or radionuclides, are unstable forms of elemental matter either man-made or found in nature. They all undergo a spontaneous process of radioactive decay through the emission of alpha and beta particles, gamma rays, and more. All of the elements on the periodic table with atomic ...

Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
Which is responsible for an element's radioactive nature, allotropy or isotopy? Isotopy. Certain isotopes of elements can be radioactive. 13 Can a single element have multiple allotropes? Yes, for instance, carbon has several allotropes like graphite, diamond, and fullerene. 10 Which has more...
