Objectives : 

Objectives Determine if a compound is molecular or ionic. Name a binary molecular compound or ionic compound using the naming rules.

Naming Compounds : 

Naming Compounds If you know the name, you can write the formula Molecular compounds Ionic compounds If you know the formula, you can write the name Molecular compounds Ionic compounds

Binary Molecular Compounds : 

Binary Molecular Compounds Write the name of the first element. Write the name of the second element, but change the ending of the word to -ide. Add prefixes, using the subscripts to guide you.

Molecular Compounds :

Ionic Compounds : 

Ionic Compounds Write the name of the cation. Element  same as element name Polyatomic cation  just write the name Write the name of the anion. Element  change the ending to -ide Polyatomic anion  just write the name No prefixes Add roman numerals if needed

Ionic Compounds : 

Ionic Compounds CaCl2

Ionic Compounds : 

Ionic Compounds CaCl2 Write the name of the cation.

Ionic Compounds : 

Ionic Compounds CaCl2 The name is the name of the element. calcium

Ionic Compounds : 

Ionic Compounds CaCl2 Write the name of the anion. calcium

Ionic Compounds : 

Ionic Compounds CaCl2 If a single element, use element name. calcium chlorine

Ionic Compounds : 

Ionic Compounds CaCl2 If a single element, change to –ide. calcium chlorine
