Part (a):
Whether is a or emitter.
Answer to Problem 27P
Solution:
is a emitter.
Explanation of Solution
Given Info:
is radioactive.
Formula used:
Binding energy is .
Solution:
decays by emission, the decay equation is .
Conclusion:
Mass is equivalent to energy. Mass in a decay reaction cannot increase. The change in mass appears as energy.
Part (b):
To Determine:
Write down the decay reaction. The maximum kinetic energy of the emitted .
Solution:
The decay reaction is . The maximum kinetic energy of the emitted is .
Given Info:
is radioactive.
Formula used:
Binding energy is .
Calculation:
decays by emission, the decay equation is .
Mass of is . Mass of is . Mass defect is
Energy released is
