235 92 U 4 2a. Determining the Mass Defect. Nuclear decay equations Brief explanation of the three forms of radioactive emission.
So for representing an alpha particle in our nuclear equation since an alpha particle has the same composition as a helium nucleus we put an He in here and it has two positive charges so we put a two down here and then a total of four nucleons so we put a four here.

This loss of matter is called the mass defect. Posted at 1328h in. _____ 4 2 He210 82 P b 2 4 H e 82 210 P b.
