Read the passage and answer the question.
Experiments performed have showed that radioactivity is a nuclear phenomenon in which an unstable nucleus undergoes a decay. This is referred to as radioactive decay. Three types of radioactive decay occur in nature :
- α-decay
- β-decay
- γ-decay
Consider that 92U238 decays via alpha decay.
What is the charge on this nuclei ?
Answer & explanation
Correct answer: option 2
The charge on this nuclei will be the proton no. i.e. 92.
