cuanchi · Answer

each of these elements can have several isotopes with different mass, different number of neutrons. The number of protons doesnt change for each of the elements and is equal to the number of electrons. http://en.wikipedia.org/wiki/Isotopes_of_nitrogen http://en.wikipedia.org/wiki/Isotopes_of_silver http://en.wikipedia.org/wiki/Isotopes_of_lead http://en.wikipedia.org/wiki/Isotopes_of_potassium

What does it mean by isotopes? @Cuanchi

jhannybean · Answer

I would think that an isotope is defined when you have the same element but it has a different number of protons and neutrons in its nucleus, much like what @Cuanchi just said.

cuanchi · Answer

Not really...
Isotopes are atoms of the same element that have the same number of protons but different number of neutrons.  @Jhannybean
The number of protons is what define an element, if and element loose or gain protons it became other element, but if an atom of an element gain or loose neutrons , still been the same element but we said that these two atoms are isotopes.
