Answer:
Isotopes of the same element have the number of protons in common
Explanation:
* Isotopes * are atoms that have the same atomic number, but different atomic mass. That is, they contain the same number of protons but different in the number of neutrons and they are in the same place within the periodic table.
It should be noted that a large part of the chemical elements have more than one isotope. Only twenty-one elements, such as sodium, have a single natural isotope. It is possible to divide the isotopes into stable isotopes and non-stable or radioactive isotopes.
For an isotope to be radioactive, it must exhibit a proportion between its amount of neutrons and protons that is not conducive to maintaining the stability of the nucleus. The notion of stability, however, is not very accurate since there are isotopes that are considered almost stable thanks to an extremely long neutralization time.
The radioactive isotope has an unstable atomic nucleus due to the balance between protons and neutrons. This same characteristic makes it emit energy when it mutates towards more stable conditions. Non-stable isotopes undergo a decay period where energy is emitted as beta, alpha or gamma rays.
