BONDING TYPES:IONIC BONDING

What is an ionic bond?How do I name ionic compounds?

How do I write the chemical formula for ionic compounds?

IONIC BONDING• Ionic Bonding: I, selfish, stealing, transfer of e-• attraction that bonds charged ions together• force behind opposites attract

++++++CATION

- - - - - -ANION

NAMING BINARY COMPOUNDS:• Binary Compounds two elements joined

together, can be ionic or covalent• IONIC = name of cation + name of anion

Cation + Anion = Compound

Bond with a Classmate!

Is this right?

Cation + AnionMg +2 S -2

Mg 2 S 2

REDUCE!

MgS

Magnesium Sulfide

NAMING COMPOUNDS WITH POLYATOMIC IONS

Naming Ionic Compounds with Transition Metals

• Roman Numeral Naming System – we will use this methodex. Manganese (II) Oxide MnO

• Latin Naming System exists – we will not use this methodex. Stannous Oxide SnO

Transition Metal Charges

Naming Ionics with Transition Metals

Writing Chemical Formulas• Assign Charges then criss x cross the numbers• DO NOT criss x cross the charges, just the #s

Ex. Magnesium ChlorideAssign Charges Mg +2 Cl-1

Criss-Cross Mg Cl2

Chemical Formula MgCl2
