A sample of rock was found to contain 8.23 mg of rubidium-87 and 0.47 mg of strontium-87.. (a) Calculate the age of the rock if the half-life of the decay of rubidium by emission is 4.71010 y. (b) If some S3887r was initially present in the rock, would the rock be younger, older, or the same age as the age calculated in (a)? Explain your answer.
The following nuclei do not lie in the band of stability. How would they be expected to decay?. (a) P1528 (b) U92235 (c) C2037a (d) L39i (e) C96245m
What are the two principal differences between nuclear reactions and ordinary chemical changes?
Technetium-99 is prepared from 98Mo. Molybdenum-SS combines with a neutron to give molybdenum-99, an unstable isotope that emits a particle to yield an excited form of technetium-99, represented as 99Tc*. This excited nucleus relaxes to the ground state, represented as 99Tc, by emitting a ray. The ground state of 99Tc then emits a particle. Write the equations for each of these nuclear reactions.
