Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Because the proton number does not change, it is still the same element with the same chemistry. Only the mass is different. The protons and electrons here are locked, so change the neutrons alone and make the target isotope.

Compared with the target, your nucleon number is:
The electrons keep orbiting. Change only the neutrons, predict, then check.
proton number Z (fixed)6
nucleon number A = Z + neutrons12
still the same element?yes, carbon
Changing neutrons changes the mass, not the element. Same protons means same chemistry.
