How can I identify atom from element? Also question about isotopes?!?
Isotopes are the atoms containing the same # of protons (atomic #) and different # of neutrons (mass #). Isotopes should be compared with different atoms of the same element. Does this mean that I can use other elements other than carbon? because I only had that as an example: C12, C13, C14. The last two are not in the periodic table? Anyway, can I use nitrogen as an isotope or any other element and it just has to be the same element to have the same # of protons? Does this make all elements in the periodic table considered to be isotopes?
