Strontium - Wikipedia. Isotopes. Natural strontium is a mixture of four stable isotopes: 84 Sr, 86 Sr, 87 Sr, and 88 Sr. Their abundance increases with increasing mass number and the heaviest, 88 Sr, makes up about 82.6% of all natural strontium, though the abundance varies due to the production of radiogenic 87 Sr as the daughter of long-lived beta-decaying 87 Rb.
