Bohr -Rutherford Diagrams

  • shows number and location of subatomic particles

Lewis Dot Diagrams

  • shows valence electrons on valence shells

Ions

  • ion = a charged atom that gains or loses electrons to get a full outer shell

  • all noble gases are stable

    • electron configuration

Metals

  • loses electrons, become cations (positive)

  • imbalance of protons and electrons

  • easier to lose one than gain seven

  • charge = group number

Non-Metals

  • gain electrons, become anions (negative)

  • imbalance of protons and electrons

  • charge = group number - 8
