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 :
Consider that 92U238 decays via alpha decay. |
What is the charge on this nuclei ? |
-92 +92 zero +46 |
+92 |
The charge on this nuclei will be the proton no. i.e. 92. |
