1 Unit 1 Chemical Bonding: Ionic 1.6 What is in a name of an ionic compound? AIM: How do we name ionic compounds? DO NOW: Write the chemical formula for the following two ions when they bond: CuSO 4 Cu (SO 4 )

2 CATIONS and ANIONS CATION  POSITIVELY CHARGED ION »USUALLY METAL ANION  NEGATIVELY CHARGED ION »USUALLY NON-METAL

3 IONIC COMPOUNDS LOOK AT THE LIST OF COMPOUNDS PRESENTED 1.NAME SIMILARITIES YOU NOTICE 2.WRITE DOWN THE SIMILARITIES IN THE BOX PROVIDED All end in -ideSIMILARITY:Cation named first Calcium SulfideAluminum Iodide Potassium Oxide Lithium Chloride Metal named firstNon-Metal named second

4 HOW DO WE NAME IONIC COMPOUNDS? STEPSDESCRIPTIONEXAMPLE: NaCl IDENTIFY THE ATOMS USED IONS FORMED ADD THE -IDE Find the names of the atoms used on the Periodic Table Na  Sodium Cl  Chlorine Na +  Cation Cl -  Anion SodiumChlorine Chloride CATION is first ANION is second CATION  name stays the same ANION  ending changes to -ide

5 IONIC COMPOUNDS LOOK AT THE LIST OF COMPOUNDS PRESENTED 1.NAME SIMILARITIES YOU NOTICE 2.WRITE DOWN THE SIMILARITIES IN THE BOX PROVIDED All end in –ate or iteSIMILARITY: Metal first Berrylium SulfateSodium Nitrite Magnesium nitrate Sodium Dichromate Polyatomic ion named second

6 HOW DO WE NAME COMPOUNDS WITH POLYATOMIC IONS? STEPSDESCRIPTIONEXAMPLE: NaNO 2 IDENTIFY THE ATOMS USED IONS FORMED WRITE IT OUT (Depending on the oxidation states) Find the names of the atoms used on the Periodic Table Na  Sodium NO 2  Nitrite Na +  Cation NO 2 -  Anion SodiumNitrite CATION (metal) is first ANION is second CATION  name stays the same ANION  polyatomic ion stays the same

7 HOW DO WE WRITE FORMULAS WHEN NAME IS PROVIDED? STEPSDESCRIPTIONEXAMPLE: CALCIUM IODIDE IDENTIFY THE ATOMS USED IONS FORMED CRISS-CROSS RULE Find the names of the atoms used on the Periodic Table Calcium  Ca Iodide  I Ca  Cation  Ca +2 I  Anion  I - Ca +2 I-I- CATION (metal) is first ANION is second Exponent becomes the subscript of the opposing ion Ca 1 I2I2 CaI2I2

8 NEXT Complete the INDEPENDENT PRACTICE When you are done, you may work on the following: YOUR LAB - you will be allowed to use this on your quizzes and (some of) your exams
