Question
Chapter 16, Problem 51UTC
Interpretation Introduction
Interpretation:
The new nucleus after the emission of a positron needs to be determined.
Concept introduction:
A proton is turned into a neutron and a positron (with a positive charge) leaves the nucleus.
Positron emission happens when a nucleus emits a positron
Expert Solution & Answer
Answer to Problem 51UTC
Solution:
Explanation of Solution
Positron emission happens when a nucleus emits a positron
At the beginning there are 6 protons and 5 neutrons, after the emission there are 5 protons and 6 neutrons.
Conclusion
Thus, positron emission happens when a nucleus emits a positron
