Use this chart along with the Table of the Elements to
determine the progeny (and ancestor) of an isotope.
For example; we know
decay mode tells us the mass # decreases by 4 (238 goes to
234) and the Z # decreases by two (94 goes to 92). The
element with a Z # of 92 is Uranium.
As another example; we know Cl is a beta emitter. The beta
decay mode tells us the mass # stays the same and the Z #
increases by one (17 goes to 18). The element with a Z #
of 18 is Argon.
