Americium-241 is used in some smoke detectors. It is an alpha emitter with a  half-life of 432 years. How long will it take in years for 38.0 %% of an Am-241 sample to decay?

An unknown radioactive substance has a half-life of 3.20 hourshours . If  23.0 gg of the substance is currently present, what mass A0A0 was present 8.00 hours ago?

None

The half-life for radioactive element Z is 6 hours. If there is originally 50 g of sample Z, how much will be left after 15 hours?

I have a homework question for which the correct answer is given.  However, I don't understand why there isn't a 1,2-hydride shift during the carbocation phase of the reaction to make the carbocation more stable.

Gold-198 is used in the diagnosis of liver problems. The half-life of 198-Au is 2.69 days. How long will it take for the Au-198 to reduce to 17% of its original amount?
