Radioactivity

Mass number & Atomic Number of the most stable member of an isobaric series

$begin mathsize 36px style Z equals fraction numerator 38 A over denominator 0.6 A to the power of begin display style bevelled 2 over 3 end style end exponent plus 76 end fraction end style$

A = Mass number; Z= Atomic Number = Number of protons present in the nucleus
