Question
Chapter 17, Problem 17P
Interpretation Introduction
Interpretation:
To write the reactions for 32P and 35S decay and find the remaining percentage of isotopes after 100 days.
Introduction:
Both these two isotopes undergo beta emission decay. Beta particles are high energy electrons. One neutron is converted to a proton releasing a beta particle. Energy released in this nuclear reaction is stored in the beta particle. Thus, beta particle is highly energized. It is emitted as a high energy beta particle. As a result of this event, number of protons increase by one and the neutrons decreased by one inside the nucleus.
