Question

Omg I need to write the nuclear equation for these things :) Can I get some help please? Awesome, thanks!

Answer 1

`""^235U -> ""^231Th + ""^4He`

Explanation:

Alpha decay: A type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into an atom with a mass number that is reduced by four and an atomic number that is reduced by two.

If `X` atom with mass number `A` and atomic number `Z` undergoing alpha-decay then it’s nuclear equation is written as

`""_Z^A X -> ""_(Z-2)^(A-4) Y + ""_2^4 He`
