REMEDIATION: PROPERTIES OF H2O
3. Which property is water is essential to providing plants with the vital minerals and nutrients they need?
4. Why does solid water (ice) float? Why is this unique to water?
REMEDIATION: PROPERTIES OF H2O
5.Water is the only known substance to naturally exist as a solid, liquid and gas. Pick one of these states of matter and explain why it is essential to life on Earth?
FORMING AND NAMING IONIC COMPOUNDSOBJECTIVES:
1.PREDICT THE FORMATION OF IONIC COMPOUNDS
2.USING THE NOMENCLATURE RULES, NAME OR PREDICT FORMULAS OF COMPOUNDS WHEN GIVEN AN IONIC COMPOUND
GUIDING QUESTION
•How does road salt keep roads from icing over?
WARM UP1.For each of the following
compounds identify which type of bond exists between the elements
a.Fe2O3
b.CuCl
c.NH3
d.HgO
e.PO43-
f. H2SO4
2. Draw the Lewis Structure for:
a. Na b. Cl
3. Write the electron configuration for Cl-
4. Write the noble gas shorthand for K+
5. Which element in its ground state has the same electron configuration as your answer to 3 & 4??
IONIC BOND
•Definition: A bond between a metal and a non-metal; valence electrons are transferred from the metal to the non-metal
M + N.M.
PROPERTIES OF IONIC COMPOUNDS
•High Melting & Boiling Points
•Dissolve in Water Causes the melting point of water to drop
•Conduct electricity when melted or dissolved in water
•Create huge lattice (Chain) Structures
If we could zoom in SUPER close
MAKING AN IONIC COMPOUND
A metal and a non-metal
Low Ionization EnergyLeft side of the periodic table
High electronegativityRight side of the periodic table
Sodium (Na)
Chlorine (Cl)
Wants an electron
Wants to get rid of an electron
THE OCTET RULE
•Why do atoms gain or lose electrons?
• The Octet Rule:
•Definition: Atoms will lose or gain valence electrons to get to 8 (full valence shell)
•What will happen to each of these elements? (How many electrons will be lost/gained)1.B2.Br
3.Mg
4.Li
5.Xe
MAKING AN IONIC COMPOUND
Sodium (Na)
Chlorine (Cl)
MAKING AN IONIC COMPOUND
Sodium (Na)
Chlorine (Cl)
MAKING AN IONIC COMPOUND
Cation: a metallic element that loses electrons; has a positive charge
Anion: a non-metal that is highly electronegative that gains electrons; has a negative charge
MAKING AN IONIC COMPOUND
Sometimes its not as easy as NaCl…
3 Steps:1. Draw the Lewis Dot
Structure for each element
2. Determine which element will lose electrons and which will gain electrons
3. Draw the transfer electrons from the cation to the anion, add another atom as needed
MAKING AN IONIC COMPOUND
•Show the formation and resulting ions of
MgCl21. Draw the Lewis Dot Structure for each element
2. Determine which element will lose electrons and which will gain electrons
3. Transfer electrons from the cation to the anion, add another atom as needed
Mg Cl
Cl
YOU DO: MAKE IONIC COMPOUNDS
•Show the formation and resulting ions of:1. MgS
2.BeBr2
•Write the formula for the ionic compound that results from the bonding of the following elements1.Cs and I
2.Ca and F
1. Draw the Lewis Dot Structure for each element
2. Determine which element will lose electrons and which will gain electrons
3. Transfer electrons from the cation to the anion, add another atom as needed
NAMING TYPE 1 IONIC COMPOUNDS
•The cation is named first as it appears on the periodic table
•The anion is named second with the root word plus the suffix “ide”
• Example: KBr
•K is the cation
•Br is the anion
Based off our rules we would name this as:
Potassium Bromide
IMPORTANT:
The Cation is an Alkai Metal or Alkaline Earth Metal (NOT H)
PARTNER PRACTICE (8 MIN)Name or write the formula for each of the following:
1.LiF
2.NaCl
3.Potassium Chloride
4.BeO
5.Magnesium Sulfide
6.KI that is an I for Iodine
TABLE GROUP ANSWERS:
1.Lithium Fluoride
2.Sodium Chloride
3.KCl
4.Beryllium Oxide
5.MgS
6.Potassium Iodide
NAMING TYPE 2 IONIC COMPOUNDS
•Similar to naming Type 1 Compounds:• The cation is named first as
it appears on the periodic table
• The anion is named second with the root word plus the suffix “ide”
•BUT…•Roman numerals are used
to represent the charge for the cation
IMPORTANT:
The Cation is a transition metal
NAMING TYPE 2 IONIC COMPOUNDS
•Example 1: What is the name of the compound
Fe2O3
•Example 2: What is the formula of Zinc (II) Chloride?
IMPORTANT:
The Cation is a transition metal
PARTNER PRACTICE (8 MIN)
Write the name or formula for each compound
1.CuCl2
2.FeCl3
3.Lead (III) Iodide
4.MnF3
5.CoBr3
ANSWERS TO PROBLEMS
1.Copper (II) Chloride
2. Iron (III) Chloride
3. PbI3
4. Manganese (III) Fluoride
5. Cobalt (III) Bromide
