1. Physical Science Final Review #3
Naming & Bonding

2. Bonding Basics Covalent Ionic Metallic SHARES ELECTRONS
NONMETAL + NONMETAL
STRONGEST BOND!
Ionic
TRANSFERS ELECTRONS
METAL + NONMETAL
CATION + ANION
Cation= + charge , loses electrons
Anion= - charge, gains electrons
Metallic
METAL + METAL

3. Bonding Basics Empirical Formula: Molecular Formula Most Reduced
Example: For C10H30, the empirical formula is _______________
Molecular Formula
Actual formula
To get possible MFs for an EF, multiply the subscripts
Ex: Name 3 possible MFs for the EF of CH2 ________________________________

4. NAMING IONIC COMPOUNDS
NO PREFIXES!
For Binary (like NaF)
First element name + second element name but change the ending to –ide
NaF= __________________________
For Ternary (like Na(NO3))
First element name + polyatomic name NO changing ending
Na(NO3) = _____________________________

5. FORMULAS FOR IONIC COMPOUNDS
CROSS CHARGES ON ELEMENTS
You will be given periodic table with element charges!
Ex: Mg+2 and Cl-1
Ex: Al+3 and CO3-2

6. NAMING COVALENT COMPOUNDS
USE PREFEXIES
1= mono
2= di
3=tri
4=tetra
5=penta
6=hexa
When naming you do:
prefix (unless 1) element name + prefix (always), element name, end in ide
Examples
P2O3
IF5
CCl4
S5N6
H2O

7. Br2 I2 N2 Cl2 H2 O2 F2
Remember, these come in pairs and are named by the element name. NO PREFIXES:
Examples:
O2:
Fluorine:
Br2:
Hydrogen:
