The number of their neutrons.
This isotope is transformed in another isotope of another element.
the element is lead and the particular isotope is Pb-206
radioactive decay
It is the neutron that makes changes in atomic nuclei to change them from one isotope to another. For any given element, that element will have a fixed number of protons. It is, after all, the number of protons that determine the elemental identity. But the number of neutrons in a given element can vary, and we use the term isotope to talk about which particular atom we're investigating. That is, we apply the term isotope to speak to an atom of a given element with a certain number of neutrons in its nucleus.
It represents the mass number of that particular isotope.

Isotopes of one particular element differ only in their number of neutrons in nucleus.
Ba and Cs
It represents the mass number of that particular 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.
They cannot be compared because a proton is a part of the atom and an isotope is just a variant of a particular chemical element which is made of atoms
No.
No. An element is a type of atom; distinguished by the number of protons; an isotope might be considered a "sub-type", distinguished by the number of neutrons. In other words, different isotopes of the same element have the same number of protons, but the number of neutrons varies. This is completely unrelated to the electric charge.
