  1. How to draw atoms An atom is the smallest part of an element Particle Charge Mass Proton Electron Neutron 1 + - 1/2000 0 1

  2. How to find protons electrons and neutrons Mass Number 7 Li 3 Proton number Bottom number P E n Bottom number Top - Bottom number

  3. Need to know how to draw the first 20 atoms Nucleus 2,8,8

  4. Ions Non-metals Metals Positive!!! Negative

  5. Ionic bonding Metal and a non-metal + - Li F

  6. Ionic structure • Draw out sodium dots. • Draw out fluorine Crosses. • Work out electron movement • Re-draw ions together. • Write the formula.

  7. Sodium Fluoride + - Na F

  8. More than one!! Other elements like oxygen need 2 Electrons.

  9. Sodium Oxide 2 O Na Na 2

  10. Beryllium gives 2 electrons. 2 - 2+ - F Be F 2 Beryllium fluoride.

  11. Draw out the following • KF • LiCl • Li2O • BeCl2 • MgF2
