A. an alpha emmision is the same as the loss of a helium nucleous.
So alpha is (4,2) the first number being the mass number and the secound the atomic number.
Since our starting atom is Re(162,75) we can say that the product has a mass number of 158 and an atomic number of 73 (162-4, and 75-2)
(Re(162,75) -----> alpha(4,2) + Ta (158,73)
the ...
