1. Chemical Bonding – Naming & Drawing the bond
Chapter 13: part 2

2. 3 Types of Bonds 1. Ionic Bond – _________ valence electrons
2. Covalent Bond – _________ valence electrons
3. _________ Bond – the attraction between positively charged metal ions and the electrons around them.

3. Ionic Compounds Writing Ionic Compounds ( _______ + __________)
Write the metal with its’ charge
Write the nonmetal with its’ charge
Criss- Cross the charges
Only bring down the #, NOT the charge
Examples:
Sodium and Chlorine
Barium and Chlorine
Potassium and Oxygen
Litium and Sulfer

4. Ionic Compounds Naming Ionic Compounds Examples:
Name of Metal + nonmetal w/ ending –ide
Examples:
Sodium and Chlorine
Barium and Fluorine
Potassium and Oxygen
Lithium and Sulfur

5. Covalent Compounds Simple Covalent Compounds
When found in nature as pure elements, these seven elements exist only as two atoms covalently bonded. H2 O2 N2
Cl2
Br2 I2 F2 7 N 8 O 9 F 19 Cl 35 Br 53 I 1 H

6. Covalent Compounds
How to draw covalent molecules: using electron dot diagrams
Write the symbol of the element and place one dot around the symbol for every valence electron in the atom.
Examples:
Carbon Oxygen
Krypton Hydrogen

7. Covalent Compounds
2. Combine the elements where they can share electrons so each have a full outer shell. (The shared electrons are the covalent bond)
Examples:
Hydrogen + Chlorine
Fluorine + Fluorine
Water
Oxygen + Oxygen

8. Covalent Compounds Naming Covalent Compounds Prefixes Rules:
One = _____
Two = _____
Three = _____
Four = _____
Five = _____
Six = _____
Seven = _____
Eight= _____
Nine = _____
Ten = _____
Rules:
Prefix + name Prefix + name –ide
Rule: Do NOT use mono- on the first element
Examples: CO
CO2
C2H4
P2O5
N3P6
