Oh, this was my exact nightmare in Class 10, I'd just memorise without understanding and now I can't explain it to my bhaiya! For alpha decay, subtract 4 from mass number and 2 from atomic number; for beta decay, atomic number increases by one, mass stays same. My life lesson? Please don't just rot-learn like I did, ask your teacher 'why?'—because now, fixing a bad internet connection for my remote job feels easier than this.
