what is the difference between ATOMS and ISOTOPES ?
they both contain protons and neutrons. right? so, what makes them
different?
Isotopes are made with heavy neutrons, hence they
have higher atomic weight. Atoms are made with
light neutrons. The protons are always the same
weight. For example, fissionable uranium-235
is the uranium atom and has an atomic weight of
235 a.m.u. The more stable uranium-238 is the
uranium isotope, with an atomic weight of 238 a.m.u.
because of its heavier neutrons. Both are
considered to be uranium, because they have
the same number and weight of protons.
Hope this helps! :-)
