9. Bonding

10. Why do elements form bonds?
Every element wants a full outer energy level to satisfy the octet rule
They achieve this by gaining, losing and sharing electrons

11. Ionic Bonds

12. Ionic Bonds
Formed by the transfer of electrons from one atom to another
Generally between a metal and a nonmetal
Held together by electrostatic forces
(opposite charges attracting)

13. Properties of Ionic Compounds
Crystalline Solid at room temperature
High melting and boiling points
Soluble in water (when they dissolve in water they conduct electricity)

14. Properties of Ionic Compounds Cont.
Ionic compounds are hard, rigid and brittle
Crystalline Structure – crystal retains it shape until enough energy is applied to shift the positions and crack the crystal

15. Ionic Compounds Properties Cont.
Molten state can also conduct electricity
Solid ionic compound
Molten ionic compound
Ionic compound dissolved in water

16. Naming Ionic Compounds
Standard Naming Rules
Write the full name of the metal first
Then write the second element, take off the ending and add the suffix –ide
If the second ion is a polyatomic ion, use the full name of the ion
Examples
CaO – Calcium Oxide
BaCl2 – Barium Chloride

17. Naming Ionic Compounds
Exceptions
Transition metals can have multiple oxidation numbers
Standard naming rules apply but we need to account for the oxidation number
Two Naming Systems
Classical
Stock

18. Use the Stock Method for transition metals
Stock method - use a roman numeral
Examples
FeCl3 – Iron(III) Chloride
FeCl2 – Iron (II) Chloride
PbCl4 – Lead(IV) Chloride
We will discuss an additional method called the classical method tomorrow
Stock is more standard
