Which of the following isotopes would most likely be unstable and therefore radioactive helium-3 calcium-40 molybdenum-98 mercury-194?
Molybdenum-98 is most likely to be unstable and therefore radioactive. Isotopes with an odd number of protons or neutrons tend to be less stable, compared to isotopes with even numbers of protons and neutrons. Molybdenum-98 has an odd number of neutrons (58) which makes it more likely to be unstable.
What is the difference between radioactive and non-radioactive isotope?
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 blank it is radioactive?
When an isotope is unstable, it is said to be radioactive.
What is An unstable isotope is called what?
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.
What is an unstable isotope?
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Is helium unstable and also radioactive?
Helium is extremely stable and non radioactive
Is calcium unstable ans also radioactive?
Calcium is mostly stable
Is mercury a radioactive substance?
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

What are the unstable element?
Radioactive elements are unstable, and the shorter the half-life, the more unstable they are.

True or false unstable atom that decomposes and emits energy is called retroactive?
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
Is Mercury stable or radioactive?
It is stable, although there are heavier isotopes that could be radioactive.
What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
What is an unstable isotope?
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
