Hi,
I'm a wee bit confused here.
An isotope is an atom (or is it a molecule?) that has the same number of electrons as another atom/molecule of the same element but has a different number of nucleons, right?
For example, Cl 35 and Cl 37 are isotopes just like C 12 and C 14.
However, could someone please explain what an ion is because I can't figure it out.
Thanks,
