Isotope stability?

Question

Which isotope in each pair would you predict to be more stable? Why?

a.) 140/55 Cs or 133/55 Cs

b.) 79/35 Br or 78/35 Br

c.) 28/12 Mg or 24/12 Mg

d.) 14/7 N or 18/7 N

Answer 1

The stabler isotope is also the most common isotope. You can find the stabler isotope by looking at the periodic table. This is reflected in the atomic mass written on the periodic table.

A.) 133/55 Cs

B.) 79/35 Br

C.) 24/12 Mg

D.) 14/7 N
