No: They have the same atomic number but not the same atomic mass.
The atomic number is the same for all isotopes.
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
Different isotopes of an element have the same atomic number, they (only) differ in (atomic) mass NUMBER.
Atoms of the same element have different isotopes, differing only in number of neutrons (so differing in mass number, atomic mass).
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
isotopes always have the same? mass # & atomic #, or atomic # and atomic weight, or atomic # but different mass #'s
Same number of protons (=atomic number in the P.S.)Different number of neutronsDifferent in MASS NUMBER (=the sum of the number of protons AND neutrons, and also roughly equal to the atomic mass)fr eg isotopes of hydrogen are: H1 H2 H3their mass numbers are different but their charge number or atomic number (no.of protons) is the same. that is why isotopes have different physical but same chemical properties.
Isotopes. The isotope has the same number of protons and electrons as the regular atom, but has more (or sometimes less) neutrons, and therefore its atomic mass is more (or less, depending on whether the neutrons have increased or decreased).
They are called as isotopes in which mass number differ by emmision of radiation
Isotopes. They differ in the number of neutrons in the nucleus.
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
