är nuklid och isotop samma sak?

Klippt från engelska Wikipedia:

Nuclides vs isotopes
A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example carbon-13 with 6 protons and 7 neutrons. The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, while the isotope concept (grouping all atoms of each element) emphasizes chemical over nuclear. The neutron number has large effects on nuclear properties, but its effect on chemical reactions is negligible for most elements. Even in the case of the very lightest elements, where the ratio of neutron number to atomic number varies the most between isotopes, it usually has only a small effect, but it matters in some circumstances (for hydrogen, the lightest element, the isotope effect is large enough to affect biological systems strongly). Since isotope is the older term, it is better known than nuclide, and is still occasionally used in contexts in which nuclide might be more appropriate, such as nuclear technology and nuclear medicine.

Kortversion: Nuklid handlar om kärnan, isotop om hela atomen, men den äldre termen isotop används ibland (av historiska skäl) där man egentligen borde använda nuklid.
