What is an Isotope Practice Set?
An
isotope practice set
is a collection of exercises, questions, and problems designed to help learners understand the properties, identification, and applications of isotopes. These sets typically include a variety of question types to challenge different aspects of isotope knowledge, such as atomic structure, mass number calculations, nuclear stability, and real-world applications.Components of an Isotope Practice Set
An effective practice set generally contains:
- Multiple-choice questions (MCQs): To test recognition and basic concepts.
- Calculation problems: For determining isotopic composition, atomic and mass numbers, and relative abundances.
- Matching exercises: To pair isotopes with their properties or applications.
- Short answer questions: To explain concepts like nuclear stability or isotope use cases.
- Practical scenarios: Real-world problems involving isotope analysis in fields like medicine, archaeology, and environmental science.

Sample Questions from an Isotope Practice Set
To illustrate the types of questions you may encounter, here are some sample exercises:
Question 1:
An isotope of carbon has 6 protons and 8 neutrons. Write its isotopic notation and calculate its mass number.
Answer: The isotope has 6 protons (atomic number Z = 6) and 8 neutrons.
Isotopic notation: 14C
Mass number (A) = 6 + 8 = 14
Question 2:
If 75% of a sample of chlorine is 35Cl and 25% is 37Cl, calculate the average atomic mass of chlorine.
Solution:
Average atomic mass = (0.75 × 35) + (0.25 × 37) = 26.25 + 9.25 = 35.5 amu
Question 3:
Explain why some isotopes are radioactive while others are stable.
Answer:
Radioactive isotopes have unstable nuclei due to an imbalance of protons and neutrons, leading to nuclear decay. Stability depends on the ratio of neutrons to protons and the energy configuration of the nucleus. Stable isotopes have balanced nuclear forces that prevent decay.
