Strontium-88 at 82.6%
38There can be multiple atoms that have the same number of neutrons, these are called isotopes. The most common isotope of strontium (one of four stable isotopes), is strontium 88. This means that the number of protons and neutrons together in that isotope is 88. And since all atoms of strontium (regardless of their isotope) have 38 protons, that means that the most common isotope of strontium has 50 neutrons.
