Alpha decay reduces mass number by:
Select the correct option:
Solution
Incorrect! Answer:
4
An alpha particle (α) is equivalent to a Helium nucleus, consisting of 2 protons and 2 neutrons (24He). When a nucleus undergoes alpha decay, it ejects this particle, thereby reducing its atomic number (Z) by 2 and its mass number (A) by 4. The general reaction is: ZAX→Z−2A−4Y+24He.
