What are Isotopes?
This chemistry video tutorial answers the question - what are isotopes? Isotopes are substances that are composed of the same element but consist of different mass numbers and number of neutrons. They share the same atomic number and therefore the same number of protons. This video contains plenty of examples and practice problems associated with isotopes and writing the atomic symbol for it.
