How do unstable isotopes decay radioactively
WebAnswer (1 of 2): If you really want to understand what happens in the atomic nuclei of unstable isotopes, you have to study the weak interaction, which is responsible for the weak nuclear force (one of the four fundamental forces in the standard particle model -- others are electromagnetic force,... WebPhosphorus is abundant in biological systems and, as a radioactive isotope is almost chemically identical with stable isotopes of the same element, phosphorus-32 can be used to label biological molecules. The beta radiation emitted by the phosphorus-32 is sufficiently penetrating to be detected outside the organism or tissue which is being analysed

WebRadioactive Decay — Disintegration of the nucleus of an unstable atom by the release of radiation. Radiation — Energy moving in the form of particles or waves. Familiar radiations are heat, light, radio waves, and microwaves. … WebUnstable isotopes decay through various radioactive decay pathways, most commonly alpha decay, beta decay, or electron capture. Many other rare types of decay, such as spontaneous fission or neutron emission are known. It should be noted that all of these decay pathways may be accompanied by the subsequent emission of gamma radiation. …

WebStable isotopes do not decay over time and tend to be the most commonly found isotopes of any given element. An example to illustrate the point would be different isotopes of carbon. Common isotopes of carbon include carbon-12, carbon-13, and carbon-14, often written as 12 C, 13 C, and 14 C. These types of atoms have 6, 7, and 8 neutrons ...
