• Date: 12-14-13
• Day Plan: 1) Notes on Naming Ionic Compounds
2) Practice
3) Next week Friday Bring your Text Book
• Opener:
1) Name the following compounds
A) NaCl
Sodium Chloride
B) CO2
Carbon Dioxide
Lab Reports –
If you missed Lab the week it has effected
your grade. Please turn it into the sub
A) Writing the Chemical formula for a Compound
Step 1 – List the symbols and find the
charge of each isotope
Step 2 – Balance the charges to make a
neutral compound
Step 3 – Write the Formula
Calcium Nitride
B) Naming Binary Compound
• Composed of two elements
• Three types of Binary compounds
▫ Type I – Cation Comes from Group 1 or 2
▫ Type II – Cation comes from Transition Metals
▫ Type III – Two non- Metals (Left of the periodic Table)
Type I – Naming Ionic Compounds (pg – 95)
This type of naming is for cations in group 1 or 2
1) List Cation FIRST
▫ Keeps name of element
2) Anion SECOND
▫ Keep Root word and Add –ide ending
• Number of each element DOES NOT MATTER
• Example: NaCl
Sodium
Chloride
MgCl2
Magnesium
Chloride
Type II – Naming Ionic Compounds (pg-99)
This type of naming is for Transition metal cations
1) Name Cation & Anion Same as Type I
2) Add Roman numeral to Cation to indicate charge
3) May have to balance out equation to find charge
• Example: CoBr2
Cobalt (II)
Bromide
PbCl4
Lead (IV)
Chloride
Type III – Naming Ionic Compounds (pg-103)
This type of naming is for Non- Metals
1) Element 1 = cation while Element 2 = anion
2) Add prefixes to display the # of atoms present
3) Mono- is never used for naming the first element
• Example: SO2
Sulfur
Dioxide
P4O6
Tetraphosphorus
Hexoxide
Practice – Finding the Formula:
• Predict the formula if Oxygen and Potassium form an
ionic bond.
Practice – Finding the Formula
• What is the formula for Aluminum Bromide?
Practice Finding the Formula:
• Predict the formula if Copper(II) and Nitrogen form
and ionic bond.
Practice Naming:
• Predict the name for MgI2
• Which type of naming is this? ________________
Practice Naming
• LiBr
• Lithium Bromide
Practice Naming
• What is the name for the following formulas
A) SnS2
B) Ca3P2
C) CCl3
One of the following pairs will form an
ionic bond, one won’t. Draw out the one
that will form the bond and describe why
the other pair won’t bond.
A) Argon and Oxygen
B) Barium and Carbon
• Argon is a Nobal gas and will
not bond with Oxygen
• Type III Naming
Practice: Write the correct formula for the
compounds formed from each pair of ions
Potassium and Sulfur
Calcium and Oxygen
Practice: Which pairs of elements are
likely to form ionic compounds?
• A. Cl and Br
• B. Li and Cl
• C. K and He
• D. I and Na
