Atomic Number
-Atomic number=number of protons
atomic mass - atomic number = number of neutrons
Isotopes
-Same atomic number but different mass
For example there are 3 types of hydrogen atoms
1H 2H 3H
-Not all atoms of the same element are identical
Mass Spectrometers
-Are used to determine the abundance and mass of the isotopes of elements
-A device known as a mass spectrometer can be used to determine the relative abundance and the mass of the isotopes in an element
-Isotopes are elements that have the same atomic number(same element) but different atomic masses

This is a bit tricky because 1H isn't refering to protium. If your going to write this out you'll need to find a way to make the 1 superscriped. Its really important to distinguish this from a balancing coefficient.
