Number of protons in the nuclei of their atoms.
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
isotopes all have different numbers of neutrons compared to each other, therefore different atomic masses, but they are chemically identical
The following atoms are all variations of the element carbon 12C 13C 14C what are these variations called isotopes. Isotopes are variants of a particular chemical element.
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
29 protons
No. The most common isotope(s) of an element are often stable.
Isotopes of a element are simply versions of that same element with different count of neutron, with that in mind they take all of the isotopes of a specific element and average them together taking in account the percent abundance of each so the most common isotope is the one on the periodic table.
The proton and electron number are equal for all isotopes of the same specific element.
All the isotopes of a chemical element have the same atomic number, number of protons and 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.
All the isotopes of a chemical element have the same number of protons and electrons (in a neutral state).
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.
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
