In the case of gamma emission, the nucleus remaining will be of the same chemical element, but for alpha, beta, This property of Uranium, that it spontaneously emits radiation is called radioactivity. The radiological and chemical properties of DU can be compared to those of natural uranium, which is ubiquitously present in soil at a typical concentration of 3 mg/kg. Radioactivity is a natural phenomenon in which atoms of elements that have unstable nuclei (nuclei = plural of nucleus), ... Isotopes of an element have the same chemical properties, but they differ only in weight due to a difference in the number of neutrons. FREE Physics revision notes on Detection of Radioactivity. However, certain atoms have unstable nuclei due to an excess of either protons or neutrons, or an excess of both. RADIOACTIVITY, A NATURAL PROPERTY OF CERTAIN ATOMS In nature, the nuclei of most atoms are stable.

Examples of chemical properties are heat of combustion, flammability, toxicity, etc. 1 Radioactivity Emission of high energy photons and particles Alpha, Beta and Gamma Rays Elements heavier than lead (Z=82), are radioactive Radioactive materials emit: –alpha particles (helium nucleus) –beta particles (electrons) –gamma rays (electromagnetic radiation) How can we tell the difference between these? A chemical property is a property that is associated with chemical reactions and changes in the composition of matter. To get answer to any question related to properties of alpha,beta and gamma rays click here. Natural uranium has the same chemotoxicity, but its radi-otoxicity is 60% higher. A physical property, on the other hand, is something that can be measured or sensed, without changing the composition of the matter.
