Tungsten-181 decays by electron capture. Provide the element symbol and mass number for the product of the radioactive decay of W-181
The transformation of e capturing process of 181W is -
181W74 + 0e-1 = 181Ta73 + gamma particle
Hence, the product will be tantalum which mass no will remain same as that of tungsten i.e. 181 and atomic no. Z = 73

There are two radioactive elements, elements A and B. Element A decays into element B with a decay constant of 2/yr, and element B decays into the nonradioactive isotope of element C with a decay constant of 1/yr. An initial mass of 3 kg of element A is put into a nonradioactive container, with no other source of elements A, B, and C. How much of each of the three elements is in the container after t yr? (The decay...

22. Consider the case of a radioactive element X which decays by electron (beta) emission with a half-life of 4 days to a stable nuclide of element Z. Which of the following statements is CORRECT? (a) After 8 days the sample will consist of one-fourth element Z and three-fourths element X. (b) Element Z will weigh exactly the same as element X when decay is complete (weighed to an infinite number of significant figures). (c) 2.0 g of element X...
I only need help with part c). Thanks! As a radioactive specimen decays, its activity decreases exponentially as the number of radioactive atoms diminishes. Some radioactive species have mean lives in the millions (or even billions) of years, so their exponential decay is not readily apparent. On the other hand, many species have mean lives of minutes or hours, for their exponential decay is easily observed. According to the exponential decay law, the number of radioactive atoms that remain after...

Outside the nucleus, the neutron itself is radioactive and decays into a proton, an electron, and an antineutrino. The half-life of a neutron (mass = 1.675 × 10-27 kg) outside the nucleus is 10.4 min. On average, over what distance x would a beam of 3.39-eV neutrons travel before the number of neutrons decreased to 75.0% of its initial value? Ignore relativistic effects.
Consider a pure sample of a radioactive isotope with a mass number of 52. If the sample has mass of 33 micrograms and the isotope has a half-life of 27.5 x106 years, determine the decay rate for the sample. Give your answer in decays/secondand with 3 significant figures.
