Chemical bonds that result from the electrical attraction between large numbers of cations and anions

Cation – ?

Anion – ?

Ionic bonds – REVIEW

Ionic bonds most commonly form between …?

REVIEW

Ionic bonds are made up of charged pieces (ions) … Ions can be made up of single atoms or groups of atoms bonded together (polyatomic ions)

Binary ionic compound – ionic compound consisting of only 2 elements (monatomic ions)

Naming:

Name the cation and add an ide ending to the anion

Examples:

sodium and chlorine form…

sodium chloride

magnesium and oxygen form…

magnesium oxide

What’s a binary ionic compound?

Binary ionic compound – ionic compound consisting of only 2 elements (monatomic ions)

Bromine bonds with sodium

Cesium bonds with oxygen

Silver bonds with fluorine

Sodium bromide

Cesium oxide

Silver fluoride

What type of compounds have we learned to name?

How do you identify this type of compound?

chlorine bonds with lithium

magnesium bonds with sulfur

aluminum bonds with oxygen

Lithium bromide

Magnesium sulfide

Aluminum oxide

Problem… names do not directly indicate ratio of ions…

Answer… empirical formula

Li2O NaCl MgF2

Determining formulas – Crisscross method

Determining formulas – Crisscross method

1. determine charges

2. Take away the +/- and crisscross them to determine subscripts

Determine the empirical formula for an ionic compound containing…

potassium and fluorine

calcium and fluorine

cesium and sulfur

aluminum and oxygen

Name the compounds formed when the following elements bond:

1.Calcium and fluorine

2.Chlorine and strontium

3.Silver and oxygen

Write the formulas for the following compounds:

1.Lithium bromide

2.Barium chloride

3.Sodium oxide

Throwing in the transition metals:

Use roman numerals if more than one charge is possible

Roman numeral = charge, if none use sheet, then same as binary ionic compounds

Binary ionic compound – ionic compound consisting of only 2 elements (monatomic ions)

Binary Compound – A compound with 2 elements

more than 2 atoms = OK (CaF2)

more than 2 elements NOT ok (NaCrO4)

Throwing in polyatomic ions:

If formula has more than 2 eles.

Names do not change (no ide-ending)!

a non-ide ending should clue

you in (memorize hydroxide + CN-1)

more than one ion = parenthesis

1. Explain how you would

determine the name for Pb(CO3)2.

DETAILED EXPLANATION! What is the name?

1. Is a compound of C bonded to H an ionic compound? WHY or WHY NOT?2. Name me: +2 ion of Copper and a bromine ion combine3. Write the formula for the ionic compound in # 2

1.Write the formulas for the following:Cuprous Sulfide

Ferric Carbonate

Ammonium Nitrite2.Write the names for the

following:K3BO3

Co(NO2)3

Using Lewis dots to represent bonds (Lewis dots for compounds):

Na Cl

Na ClShared electrons (bonds) are represented with a line

Naming:

Acids are named for their anions

Binary: hydro – anion base – ic ending – the word “acid”

Acid - Compound that yields H+ ions (always starts with an H) – molecular compounds that act like ionics

Naming:

Acids are named for their anions

Binary: hydro – anion base – ic ending – the word “acid”

Non-binary: ate ending becomes ic, ite ending becomes ous

Examples:HF HBr HNO3 HNO2

Naming:

Acids are named for their anions

Binary: hydro – anion base – ic ending – the word “acid”

Non-binary: ate ending becomes ic, ite ending becomes ous

Examples:Hydrochloric acid

Sulfurous acid

HCl = hydrochloric acid

HNO3 = nitric acid

HC2H3O2 = acetic acid

H2SO4 = sulfuric acid

H3PO4 = phosphoric acid

Binary Molecular CompoundsBased on Prefixes

1. Less electronegative first – prefix only if more than one atom

2. Second element – prefix, root of name, ending ide (if only two elements)

3.o or a @ the end of prefix is dropped if name begins with a vowel (monooxide, monoxide)
