An isotope is unstable because isotopes are only atoms with a change in the number of neutrons. For an atom to become stable, it should have the maximum number of electrons it can have in its outer most shell, but since isotopes only deal with neutrons, this problem is not dealt with in this case. When there is a change in the number of electrons, it is called a ion. It can become stable through ionic bonding, covalent bonding and metallic bonding, depending on the two elements that are meant to bond.
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
Some isotopes are stable, others are unstable.
All the isotopes of americium are radioactive and unstable.
Unstable isotopes can be chemically reactive.
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Hydrogen has 1 unstable isotope, and 2 stable isotopes.
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
Unstable isotopes become more stable isotopes or different elements when they decay through processes such as alpha or beta decay. The decay results in the emission of radiation in the form of alpha or beta particles and gamma rays.
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
