92U238nucleus emits two α-particles and two β-particles and transforms into a thorium nucleus. Which of the following is the mass number and atomic number of the thorium nucleus so produced?
Correct answer: A. 230, 90
- A. 230, 90
- B. 234, 90
- C. 230. 88
- D. 234, 88
Explanation
The equation can be written as:23892U → 23090Th + 242He + 2 0-1e

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.
