Radioactivity is a:(I) Spontaneous activity (II) Chemical property (III) Self-disintegration property
Correct answer: C. I and III
- A. I and II
- B. II and III
- C. I and III
- D. I, II and III
Explanation
Radioactivity is a spontaneous activity (I) because it occurs without external influence and a self-disintegration property (III) because radioactive substances undergo decay over time. It is not a chemical property (II).

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
