THIS U MIGHT KNOW!! but im just sharing wid u !!
in nuke probs r ther askin u to find the no of alfa or beta emitted rite?
for that dont rack ur brain jus rite the eqn
nucleus + particle = prod+ X alfa + Y beta
to find the no of alfa
equate the mass nos in the eqn
massno of (nucleus+ particle) = mass no of ( product + x * 2 + 0) alfa has mass no 4 and beta has 0
u will get x and u can get no of alfa particles
for beta equate the atomic nos ,u know x and hence u will noe y so no of beta
any way u will b knowing this :)
cheers!!!!!
rate if useful
