Naming Type I and II Binary Ionic Compounds

Rules for Naming Type I and II Binary Ionic Compounds

RULES FOR NAMING TYPE I BINARY IONIC COMPOUND

[Alkali/Alkali Earth (cation) + Non Metal (anion)]

RULES FOR NAMING TYPE II BINARY IONIC COMPOUND

[Transition Metal(cation) + Non Metal(anion)]

1. Cation is named before anion

2. Cation retains the full name

3. Anion drops suffix "-ine" and adds suffix "-ide"

2. Cation retains the full name

3. Determine the charge of the cation and specify

by a Roman numeral in parentheses

4. Anion drops suffix "-ine" and adds suffix "-ide"

Cation full name + Anion root + -ide

Cation full name + (charge in Roman Numeral) + Anion root + -ide

NaCl= sodium chloride

Rb₂O= rubidium oxide

SrI₂= strontium iodide

K₂S= potassium sulfide

CuCl=copper(I) chloride

Fe₂O₃= iron (III) oxide

MnO₂= manganese (IV) oxide

PbCl₄= lead (IV) chloride

Exercise 1 for Naming Type I and II Binary Ionic Compounds

Directions: Using the periodic table, name the binary ionic compounds listed below. Both type I and II binary ionic compounds are listed.

Note: If you are having problems determining the charge of a Type II cation, proceed to the video below
