Ionic Compounds Unit 6: Nomenclature Lesson Essential Questions: How doI write I name an ionic How do a formula for compound? an ionic compound? Writing Names of Binary Ionic

Compounds Ex. BaO Barium Oxide You know it is aof Binary 1. Write the Name the first element Ionic Compound (cation) as is. because it contains 2. Change the ending of two

elements the(Bi) second element and one element (anion) to ide.is a metal and the other is a nonmetal. Writing Names of Binary Ionic Compounds 1. Write the Name of the first element (cation) as is.

2. Change the ending of the second element (anion) to ide. Ex. MgI2 Magnesium Iodide Writing Names of Ionic Compounds with Polyatomic Ions Ex. MgIO3 Magnesium Iodate 1. Write

the it Name You know is aof the first element Polyatomic Ionic (cation) as is. Compound because it contains than 2. Write themore name of the anion. two

elements. Writing Names of Ionic Compounds with Polyatomic Ions Ex. NH4IO3 Ammonium Iodate 1. Write the it Name You know is aof

the first element Polyatomic Ionic (cation) as is. Compound because it contains than 2. Write themore name of the anion. two elements. Writing Ionic Formulas Ex. Sodium Iodide 1. Write the formula for the anion and cation

including the charges. 2. Check to see if the charges are balanced. +1-1= Net charge of zero which means it is balanced. Na +1 I -1 Writing Ionic Formulas Ex. Barium Chloride 1. Write the formula for the anion and cation including the charges. 2. Check to see if the charges are balanced.

+2-1= Net charge of +1 which means it is NOT balanced and will need a subscript. BaBaCl Cl +2 Not Balanced -1 2 What does the subscript mean? In review: remember Barium has 2 valence ande-chlorine has 7 valence eSince Barium has two bonding sites it can have two anions bonded to it becoming.

BaCl Ba 2 C l l C Writing Ionic Formulas Another way of writing a formula is by crisscrossing the charges. +2 1 2 BaCl

Ba Cl -1 2 Writing Ionic Formulas Ex. Barium Nitrate 1. Write the formula for the anion and cation including the charges. 2. Check to see if the charges are balanced. +2-1= Net charge of +1 which means it is NOT balanced and will need a subscript and parenthesis. Ba NO Ba(NO 3 3 )2

+2 Not Balanced -1 2 Writing Ionic Formulas Ex. Ammonium Sulfate 1. Write the formula for the anion and cation including the charges. 2. Check to see if the charges are balanced. +1-2= Net charge of -1 which means it is NOT balanced and will need a subscript and parenthesis. SO

NH ) SO (NH 4 4 +1 4 2 2 Not Balanced -2 Writing Ionic Formulas Ex. Ammonium Sulfate 1. Write the formula for the anion and cation including the charges. 2. Check to see if the charges are balanced. +1-2= Net charge of -1 which means it is NOT

balanced and will need a subscript and parenthesis. SO NH ) SO (NH 4 4 +1 4 2 2 Not Balanced -2 Writing Ionic Formulas Ex. Magnesium Carbonate 1. Write the formula for the anion and cation

including the charges. 2. Check to see if the charges are balanced. MgCO CO Mg 33 +2 They are Balanced -2
