No: They have the same atomic number but not the same atomic mass.
The atomic number is the same for all isotopes.
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).
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
Isotopes
Yes, isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in atomic mass. This is why the atomic mass on the periodic table is often listed as a range for an element.
They are called as isotopes in which mass number differ by emmision of radiation
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.
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.
Atoms with the same number of protons but different mass numbers are called isotopes. Isotopes have the same atomic number but different atomic weights due to variations in the number of neutrons in the nucleus.
Isotopes describe atoms with the same number of protons and different number of neutrons. These isotopes have the same atomic number but different mass numbers, resulting in variations in 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.
