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).
The atomic number is the same for all isotopes.
The atomic number is the same for the all isotopes of a chemical element.
Isotopes. They differ in the number of neutrons in the nucleus.
Isotopes
Isotopes are atoms with the same number of protons (same atomic number) but different numbers of neutrons, leading to different atomic masses. For example, carbon-12 and carbon-14 are isotopes of carbon with atomic number 6 but atomic masses of 12 and 14 respectively.
The atomic number is the same for the isotopes of a chemical element.
No: They have the same atomic number but not the same atomic mass.
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
No. Isotopes have the same atomic number, protons and electrons. They have different neutrons.
Atomic number

Not a question of why. It just is, isotopes have the same atomic number, (which means that they are all the same element) with different neutron numbers.
The atomic number is the same for all isotopes.
isotopes Atoms of the same element are called Isotopes. they have the same number of atoms (i.e. same atomic number) but different number of neutrons
