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.
The correct answer is simple. Radioactive minerals are unstable and emit radiation at a constant rate. Thay also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
Radioactive elements emit radiations and are disintegrated step-by-step.
hydrogen-1hydrogen-2carbon-12etc.
bromine (Br2)
Lead 206 (Pb)
This phenomenon is not mandatory.
A stable, nonradioactive atom must be formed.
nonradioactive
hydrogen-1hydrogen-2carbon-12etc.
bromine (Br2)
No, americium is an unstable and radioactive chemical element.
Lead, the isotope Pb 206.
This is impossible.
Lead 206 (Pb)
This phenomenon is not mandatory.
Redioactive element
Aluminium and gold, are natural chemical elements, solid metals, nonradioactive.
A stable, nonradioactive atom must be formed.
This is a radioactive chemical element.
