Lesson Worksheet: Nuclear Decay Processes Chemistry • 10th Grade
In this worksheet, we will practice identifying decay processes based on changes in nuclear charge and mass and the properties of emitted particles.
Q1:
Which of the following decay processes increases the atomic number of an atom?
- APositron emission
- B decay
- C emission
- DElectron capture
- E decay
Q2:
An atom with an atomic number of 93 undergoes a series of nuclear reactions, producing an atom with an atomic number of 82. Why must this process involve at least one decay?
- AThe change in atomic number is not a multiple of 4.
- BThe change in atomic number is negative.
- CThe change in atomic number is odd.
- DThe change in atomic number is not a multiple of 3.
- EThe change in atomic number is prime.
Q3:
An atom with a mass number of 228 undergoes a series of nuclear reactions, producing an atom with a mass number of 216. Can this process occur without decays? Why?
- AYes, the change in mass number is a multiple of 4.
- BYes, the change in mass number is not prime.
- CNo, the change in mass number is even.
- DYes, the change in mass number is even.
- ENo, the change in mass number is a multiple of 3.
