Title: The radioactive atom 40/19 K emits a beta particle to produce what new atom? Post by: Dental Geek on Apr 15, 2017 How do you work this problem?
Title: Re: The radioactive atom 40/19 K emits a beta particle to produce what new atom? Post by: dtimmons95 on Apr 16, 2017 We have Potassium 40
I believe this might help: Potassium has three isotopes, of which potassium-40 is radioactive and provides the basis for the determination of the age of rocks between 105 and 109 years old, i.e., those formed in proterozoic and cenozoic periods of geological time. The decay of potassium-40 occurs with a half life of 1.31 x 109 years, by two routes. That associated with a beta particle decay accounts for 89% of the decay: [See Attachment] |
