Beta-alpha toh bilkul clear hai, bachhon ko samjhaane mein: alpha decay mein nucleus helium atom nikaalta hai, toh atomic number 2 se ghat jaata hai, mass number 4 se. Beta decay mein neutron proton mein badalta hai, toh atomic number 1 se badh jaata hai par mass same rehta hai. Yeh equations balance karo, and khatam. Kaam toh aasaan hai, par jaise meri masala ki packets dhoondhne mein der lagti hai, waise hi tumlog bhi dhang se practice nahi karoge toh exam ke waqt confusion ho jaayega.
