Isotopes of an element differ from each other by having different numbers of neutrons. For example: 1H (hydrogen), 2H (deuterium), 3H (tritium) are isotopes. They have the same number of protons (1) but different numbers of neutrons (0, 1, and 2 respectively).
It is called an isotope.
The radioactive isotope is disintegrated in time and emit radiations.
The radioactive isotope is disintegrated in time and emit radiations.
The half life is the period of time it takes radioactive decay to transmute one half of the isotope present at the start of the period to a different isotope, usually an isotope of a different element. This period of time is different for different isotopes, with known isotope half lives ranging from femtoseconds to many billions of years.
The number of neutrons is different for each isotope.
Each isotope of beryllium has a different number of neutrons.
By striking it with neutrons.
By striking it with neutrons.
An isotope is an element with the same number of electrons and protons different number of neutrons.
An atom with a different number of neutrons is called an isotope of the original element. Isotopes have the same number of protons (and thus the same element) but different numbers of neutrons.
A different amount of neutrons.
An isotope will have the same number of protons, but a different number of neutrons than a given atom.
