COVALENT COMPOUND
NAMING INVESTIGATION
Examples of Covalent compound names
Covalent Compound names:
• PH3 : Phosphorus Trihydride
• CO : Carbon Monoxide
• N2O3 : Dinitrogen Trioxide
• CF4 : Carbon Tetrafluoride
PREFIXES! – used for covalent
compounds only!
• 1 : Mono (only
• 6 : Hexa
used for the 2nd
element!)
• 2 : Di
• 3 : Tri
• 4 : Tetra
• 5 : Penta
• 7 : Hepta
• 8 : Octa
• 9: Nona
• 10 : Deca
Rules
• 1. The first element is named first, using the
elements name.
• 2. Second element is named as an Anion
(suffix "-ide")
• 3. Prefixes are used to denote the number
of atoms
• 4. "Mono" is not used to name the first
element
Practice “-ide” ending
• Fluorine 
• Fluoride
• Chlorine 
• Chloride
• Iodine 
• Iodide
• Oxygen 
• Oxide
• Sulfur 
• Sulfide
• Phosphorus 
• Phosphide
• Selenium 
• Selenide
Example:
• SiF4
• P2O5
• C 3 H8
• N 2 F6
• NO

Na+ --> Sodium
Ca2+ --> Calcium
• 3. Anions take the elements name and ends with "-ide”

Rules For Compound to name
• 1. The Cation (positive ion) is named first, the Anion
second.
• 2. Cations take the element name then is followed by the
roman numeral charge
Ag+ --> Silver (I)

Directions: Your turn! Now YOU need to come up with a similar “quiz” that you put each compound you are working with through. You
will not always be told if a compound contains a covalent compound, transition metal or a regular metal. You will need to determine this
on your own. Use the starting of this chart to create a “quiz” to help you do so

Naming polyatomic ions
Compound  Name
1. Identify the polyatomic ion
2. Determine if the polyatomic ion is a cation
or anion
A. If Cation: Polyatomic name then
nonmetal name ending in –ide
a. Ex. NH4Cl – Ammonium Chloride
B. If Anion: name metal (if transition metal
use roman numeral) then polyatomic ion
name
a. Ex. MgSO4 – Magnesium Sulfate

How to draw the transfer of electrons
1. Draw the Lewis Dot Diagram of each
element
2. Draw arrows moving electrons from the
cation to the anion
LEWIS DOT DIAGRAMS!
Drawing Covalent Compound movement
What is the electron movement like for
covalent compounds?
They SHARE their
electrons!
How do we draw the sharing of electrons?
1. Position the atoms (least electronegative

atom in the center)
Write the other atoms around the central
atom
Count Total number of valence electrons
from the Periodic Table
Draw a single bond from the center atom
to the each of the outer atoms.
Fill in the octets
Count the number of electrons and
compare to PT count
Helpful hints:
• Each bond is worth TWO electrons
• Hydrogen and Group 17 will NEVER be the
center atom
Exceptions:
• Hydrogen only wants TWO electrons NOT
8!
• Boron only wants SIX electrons, NOT 8
Examples:
•PCl3
•CH4
•BF3
• I2
