Balancing Chemicals and Chemical Reactions

• Work though this powerpoint in composition mode
• The chemical are images that you can drag, drop,
  copy and paste.
• You will
• do training,
• group chemical of similar valance,
• make acid, bases and salts
• Explore and balance equations.

2
Training Move the Metal atoms next to the
non-metals so that they loose Their electron to
fill the gap in the non metals
3
Move the chemical to their Valance
Valence 1
Text Box
Valence -1
Valence 2
