If you had a stable element 115, then by definition there would need to be at least one non-radioactive isotope. Stable elements are those that have at least one nonradioactive isotope. Of course, the other isotopes of the element could all be radioactive.
A non-radioactive element is an element that has at least 1 isotope that is not radioactive. The means that at least one isotope has a stable nucleus that does not break down by shooting off high-energy particles.
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
If an element has one and only one stable isotope, an example is Gold.

Lead, the isotope Pb 206.
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.

Sodium chloride is a compound, not an isotope.

Deuterium is an example of natural, non-radioactive isotope; deuterium is the isotope of hydrogen with 1 proton and 1 neutron.

For example a thorium isotope is Th-231 or 23190 Th.
