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.
Iodine is a nonradioactive halogen that occurs as a solid at room temperature and pressure.
If an element has one and only one stable isotope, an example is Gold.
Element 115, also known as moscovium, is highly unstable and all of its isotopes are radioactive. It is unlikely that a stable isotope of element 115 could exist based on our current understanding of nuclear physics and the periodic table.
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.
63Cu

For example a thorium isotope is Th-231 or 23190 Th.
An example of an isotope in my house would be carbon-14, which is used in carbon dating to determine the age of organic materials.
An example with a zinc isotope: 81Zn (mass number as superscript before the chemical symbol)
