Atomic Number
- atomic number : number of protons
atomic mass - atomic number = # neutrons
( p + n ) - ( p ) = ( n )
- The nuclei of 3 isotopes of Hydrogen
Protium - Deuterium - Tritium
Protium - Deuterium - Tritium
- Isotopes - same atomic number but different mass
Mass Spectrometers
- are used to deterine the relative abundance and mass of the isotopes of elements
A nice picture or diagram of a mass spectrometer would help a lot. In addition I'd like to see an explanation of how atomic masses can have decimals.
