by having the same number of protons and electrons and so still have the same chemical properties and physical properties with the exception of being somewhat denser.
All of the isotopes of an element contain the same number of protons. They differ only in the number of neutrons.
The number of electrons is an ionization state issue, and does not affect isotopic identity.
Isotopes of a chemical element have a similar number of protons but a different number of neutrons.
The atomic number is the same for the all isotopes of a chemical element.
Technetium, Promethium, and all elements heavier then Bismuth.
Chemical reactions involve electrons - not protons or neutrons. All isotopes of the same element have an identical number of electrons (just the number of neutrons differs) and hence the chemical properties are identical/very similar.
Isotopes are alike in that they have the same number of protons (same atomic number), which means they belong to the same element. They also have similar chemical properties due to this shared atomic number. Finally, isotopes can be identified by the element's symbol followed by a hyphen and the mass number.
All the isotopes of a chemical element have the same number of protons and electrons (in a neutral state).
For the same element, isotopes have equal numbers of protons but different numbers of neutrons. Isotopes of a given element have similar chemical properties due to having the same number of electrons, which determines an element's chemical behavior.
Isotopes of a chemical element have a similar number of protons but a different number of neutrons.
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.

The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
Isotopes of a chemical element have a similar number of protons but a different number of neutrons.
They will have a different number of neutrons.
The number of protons is the same.
The atomic number is the same for the all isotopes of a chemical element.
There is no group specified so it is not possible to be sure about this answer but all isotopes of promethium are radioactive.
