Expert Solution & Answer
Chapter 16, Problem 11RQ
Solution
To determine: The changes in the atomic number when a nucleus emits an alpha particle and when it emits a beta particle.
Answer:
Atomic number of the nucleus decreases by 2 in alpha particle emission and the atomic number of the nucleus increases by 2 in beta particle emission.
Explanation:
When alpha particle is emitted from the nucleus, then the atomic number of the parental nucleus is decreased by 2. The alpha particle is the combination of two protons as well as two neutrons. Beta particle is released from an atom when the neutron present in the nucleus of any atom converts itself into the proton. Due to the increased number of proton, the atomic number of element increases, and thus the atomic number is increased by 1 when beta particle is emitted.
Conclusion:
Therefore, the atomic number of the nucleus decreases by 2 in alpha particle emission and the atomic number of the nucleus increases by 2 in beta particle emission.
