• 2. FIND THE NUMBER OF P, N AND e-
• 3. DRAW IT
• ELEMENTS
• C, Na, Ne, O, H, N, Cl, He, Ar

2
MOLECULES

• TWO OR MORE ATOMS BONDED TOGETHER!
• CAN BE WITH TWO OF THE SAME ATOMS, OR TWO
  DIFFERENT ATOMS.
• EXAMPLES
• O2 H20

3
COMPOUNDS

• A CHEMICAL SUBSTANCE COMPOSED OF TWO OR MORE
  DIFFERENT ELEMENTS.
• CAN BE SEPERATED INTO SIMPLER SUBSTANCES
• E.G. ELECTROLYSIS ELECTRICITY CAN SEPARATE
  WATER (H20 INTO H2 AND O2)

4
COMPOUNDS

• TWO TYPES
• 1 ORGANIC COMPOUND
• CONTAINS CARBON AND MADE BY LIVING ORGANISMS
• 2 INORGANIC COMPONDS
• DOES NOT CONTAIN CARBON AND IS NOT MADE BY LIVING
  ORGANISMS

BONDING

• ALL AN ATOM WANTS IS TO BE HAPPY!!!!
• HOW DOES AN ATOM GET HAPPY?

6
BONDING

• A NEUTRAL ATOM WILL SACRIFICE ITS NEUTRALITY TO
  BECOME HAPPY.
• THEY CAN EITHER SHARE e- OR EXCHANGE e-
• Sharing e- COVALENT BONDING
• Exchanging e- IONIC BONDING

EXAMPLES

• IONIC BONDING the electrical attraction of two
  oppositely charged ions
