While studying the properties of a sample of material obtained from an excavation site, you discover an isotope of element W, 176 W. 98 Element W undergoes a series of decays until eventually a stable isotope is reached. Write the equations for the following nuclear reactions: Element W decays to release a gamma ray, The daughter nuclei of the nuclear reaction stated in question 2) b) i) decay to release a beta particle, and The daughter nuclei of the nuclear reaction stated in question 2) b) ii) decay to release an alpha particle. At the time of discovery at the excavation site, a sample of the isotope had 543000 radioactive nuclides and a corresponding activity of 350 Bq. Calculate the half-life of the isotope. The sample is transported from the excavation site to the laboratory. On arrival to the laboratory, its activity is 120 Bq. Calculate The time taken to reach the laboratory, and The number of radioactive nuclides left on arrival at the laboratory.
Radioactive decay
The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. This periodic table's elements come in a variety of shapes and sizes. Several of these kinds are stable like nitrogen-14, hydrogen-2, and potassium-40, whereas others are not like uranium-238. In nature, one of the most stable phases of an element is usually the most prevalent. Every element, meanwhile, has an unstable state. Unstable variants are radioactive and release ionizing radiation. Certain elements, including uranium, have no stable forms and are constantly radioactive. Radionuclides are elements that release ionizing radiation.
Artificial Radioactivity
The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.
