You can use a mass spectrometer, that is it detects the mass of the particle based on inertia. As isotopes differ from each other in the number of neutrons they have, a difference in charge cannot be detected.
Radioactive decay is the process in which one isotope is changed into another isotope.
subtract the number of protons from the number of electrons. The above answer does not answer the question!!
This isotope is transformed in another isotope of another element.
The number of their neutrons.
No.

The number of neutrons in it.
It is neutron
This isotope is transformed in another isotope of another element.
The number of their neutrons.
No.
An element alwys has the same number of electrons and protons no matter what the isotope - so the answer is the neutrons determine the isotope.
Isotope
Rutherfordium is one atom; of course each isotope has another number of neutrons.
isotope
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
