- Atomic # - # of protons
- Atomic mass - atomic number = # of Neutrons
- Isotopes - same atom but different mass
- For example, there are 3 types of chlorine atoms (35H, 36H, and 37H)
- Are used to determine the abundance ad mass of the isotopes of the element
- A device known as a mass spectrometer can be used to determine the "relative abudance" and the "mass" of the "isotopes" of the elements
I think this topic could use a bit more of an explanation. For example what do each of the numbers on the periodic table represent? How do we identify atomic number, atomic mass and the number of neutrons?
