What is an unstable isotope?
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
When an isotope is blank it is radioactive?
When an isotope is unstable, it is said to be radioactive.
What is another term for an atom that is unstable?
isotope
What do isotope and half life have in common?
Each (unstable) isotope has a distinctive half-life.
Hydrogen has how many unstable isotopes?
Hydrogen has 1 unstable isotope, and 2 stable isotopes.
When a unstable isotope decays the daughter isotope that result is always a stable isotope true or false?
False. When an unstable isotope decays, the resulting daughter isotope may or may not be stable. Some daughter isotopes are stable, while others may still be radioactive and undergo further decay.
What best describes a radioisotope?
its nucleus is unstable
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.
Are All isotope unstable?
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
Is it possible to determine exactly when a particular unstable isotope will begin to decay?
No. The time it will take for an individual unstable atom to decay is completely random and impossible to predict. However, because there are so many atoms in a sample (6.02x1023 in one mole) it is possible to observe the half-life of the atoms. The half-life is the time that it will take for half of the atoms in a sample of a radioactive isotope to decay into another element or isotope. This is a constant property of the isotope and does not depend on the sample size.
What do you call an element with unstable nucleus?
Radioactive isotope, or radioisotope.
What is an unstable atom that emits energy called?
This is a radioactive isotope.
