Chemistry

1. Atoms

   • Protons
     • Positive +1
     • 1 mass
   • Electrons
     • Negative - 1
     • 1/1840 mass
   • Neutron
     • Neutral
     • 1 mass
   • Atomic number
     • The number of protons in the nucleus
     • The atom is neutral so there will be the same number of protons
   • Atomic Mass
     • Protons + neutrons
   • Isotopes
     • Have the same number of protons and electrons but a different amount of neutrons
