• 1. Binary Compounds – Naming – Ending: Replace with –ide– NaCl (sodium chloride)
• 2. Writing – Oxidation numbers– Criss-cross method
• Name the following: – MgCl2– K2O
• Write the following compounds – Sodium fluoride – Aluminum chloride
• 1. Naming– Polyatomic ions – NaOH (sodium hydroxide)
• 2. Writing– Criss-Cross and oxidation numbers
• 1. Determine the initial number of individual atoms on both – List numbers
• 2. Balance by inspection
• Rules– 1. Use oxidation numbers to write
individual compounds – 2. For products, you must write ‘new’
compounds using oxidation numbers
– 3. Write states of matter if applicable– 4. Identify the type of chemical reaction
• Sodium metal + chlorine gas ----- solid sodium chloride.
• Copper metal + aqueous silver nitrate ---- silver metal + copper (I) nitrate
• 1. You must know the classification type.
• 2. Write compounds individually – Ignore how the atoms were written on
the reactant side
