  1. IONS...

  2. red and green are opposites

  3. assume red and green cancel each other net color = neutral

  4. take away one red

  5. take away one red net color = 1 green

  6. take away two red

  7. take away two red net color = 2 green

  8. net color = neutral

  9. net color = 2 red

  10. in this arrangement…

  11. green is trapped inside. Only red balls can be added or taken away…

  12. color = 2 green

  13. color = 1 red

  14. color = ?

  15. 3 red

  16. color = ?

  17. 3 green

  18. What does that have to do with chemistry??

  19. In order to understand what ions are, we need to know that…

  20. + + + + + the particles that make up atoms have either positive or negative charge

  21. + + + + + positive and negative are opposites they cancel each other out

  22. + + + + + net charge = zero

  23. + the positive (+) particle is called a proton

  24. the negative (-) particle is called an electron

  25. + + + + + in an atom, protons ( ) are in the center and electrons ( ) are on the outside +

  26. + + + + + only electrons ( ) can be added or taken away

  27. + + + + + this is an atom with 5 electrons and 5 protons

  28. + + + + + the atom is neutral net charge = zero

  29. + + + + + 5 (-) and 5 (+) = zero charge (neutral)

  30. + + + + +

  31. + + + + +

  32. + + + + + charge = ?

  33. + + + + + charge = 1- (one minus)

  34. + + + + +

  35. + + + + +

  36. + + + + charge = ?

  37. + + + + + 2+ (two plus)

  38. WHEN REMOVING ELECTRONS

  39. WHEN REMOVING ELECTRONS THE RESULTING CHARGE IS POSITIVE

  40. WHEN REMOVING ELECTRONS THE RESULTING CHARGE IS POSITIVE 1+ neutral

  41. WHEN ADDING ELECTRONS

  42. WHEN ADDING ELECTRONS THE RESULTING CHARGE IS NEGATIVE
