No the element Mercury is not Radioactive.
None of the mercury ordinarily found in nature is radioactive. Like all elements, there are synthetic radioactive isotopes of mercury.
Not really. It has tiny amounts of radioactive material, but probably less than you'd find just walking around on earth.
Mercury is stable and not radioactive
NO
Mercury-194
As a radioactive and unstable element roentgenium can be dangerous.
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.
When an isotope is unstable, it is said to be radioactive.
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
Helium is extremely stable and non radioactive
Mercury-194
Calcium is mostly stable
An unstable atom is a radioactive atom.
As a radioactive and unstable element roentgenium can be dangerous.
Unstable atoms are said to be radioactive
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.
When an isotope is unstable, it is said to be radioactive.
Radioactive elements are unstable, and the shorter the half-life, the more unstable they are.
No, mercury is not radioactivally unstable. It is an inert metal that exists in liquid form at room temperature but is extremely toxic to both animals and plant life. To be classified as radioactive, a substance must undergo nuclear decay (part of the nucleus breaks away) at a regular rate and mercury does not undergo this
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
It is stable, although there are heavier isotopes that could be radioactive.
