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

look frend,shortcuts are not helpful to you always......
digestion of concept is all u require. nuclear chem. , ull mostly be tested in sums related to half life, no .of particles emitted, and direct conceptual theory questions.

all together,there are hardly 10 basic formulae in the chapter, look out and note thm down on paper, and make sure that u revise them at leest once a day and if possible, do only one sum on each of the ten formulae. do this for only 5 dayz, nd look, ull be rocking radioactivity.

It doesn't work to leap a twenty-foot chasm in two ten-foot jumps.

There are three kinds of people; those that make things happen, those that watch things happen and those who don't know what's happening.
