Naming Molecular Compounds

Objective:

The student will record lecture notes on naming ionic compounds then practice naming and formula writing in a class activity.

Agenda:

Naming Ionic compounds– Lecture

Naming Ionic compounds HW


Molecular nomenclature

Molecular Nomenclature

Prefix System (binary compounds)

1.Less e-neg atom comes first.

2.Add prefixes to indicate # of atoms. Omit mono- prefix on first element.

3.Change the ending of the second element to -ide.
