1. Naming Covalent Compounds
When it is all NONMETALS

2. Formed between a metal and a non- metal
Review: Ionic Bonds
Formed between a metal and a non- metal

3. Types of Covalent Bonds
Formed between two nonmetals in 14, 15, 16, and 17
Nonmetals have high electronegativity values
Electrons are shared
single bond shares one pair electrons
double bond shares two pairs electrons
triple bond shares three pairs electrons

4. Diatomic Elements Gases that exist as diatomic molecules
are H2, F2, N2, O2, Cl2, Br2, I2
They are simply given their elements name.
Exist this way only when not in compounds
“I Have No BRight Or CLever Friends.”

5. Learning Check
Use the name of the element to name the following diatomic molecules. H2 hydrogen N2 nitrogen Cl2 _______________ O2 _______________ I2 _______________

6. Naming Covalent Compounds
Two nonmetals
Step 1: Name each element
Step 2: End the last element in –ide
Step 3: Add prefixes to show more than 1 atom
Prefixes
mon hexa 6
di 2 hepta 7
tri 3 octa 8
tetra 4 nona 9
penta 5 deca 10

7. Learning check CO2 carbon _______________
