Chemistry radioactive decay
WebPROBLEM \(\PageIndex{10}\) Technetium-99 is prepared from 98 Mo. Molybdenum-98 combines with a neutron to give molybdenum-99, an unstable isotope that emits a β particle to yield an excited form of technetium-99, represented as 99 Tc *.This excited nucleus relaxes to the ground state, represented as 99 Tc, by emitting a γ ray. The ground state … WebThe rate for radioactive decay is: decay rate = λN with λ = the decay constant for the particular radioisotope. The decay constant, λ, which is the same as a rate constant discussed in the kinetics chapter. It is possible to express the decay constant in …
