Answer
Isotopes have the same number of protons and electrons but different numbers of neutrons.
Solution
Isotopes are atoms of the same element, so by definition they have the same number of protons. In neutral atoms, they also have the same number of electrons. What distinguishes isotopes is the difference in the number of neutrons.
Thus, all the listed statements are correct.

Isotopes are like siblings in the family of elements but with a twist! While they share the same number of protons and electrons, which defines them as the same element, their neutron numbers differ. This difference in neutron count leads to variations in atomic mass, giving rise to distinct isotopes – some stable, some radioactive. In the real world, isotopes have exciting applications! For example, carbon-14 is used in radiocarbon dating, helping archaeologists determine the age of ancient artifacts. Meanwhile, isotopes like uranium-235 are pivotal in nuclear reactors and energy production, showing just how vital these atomic variations are to science and technology!
