Naming Ionic Compounds Step 1: Get out a Periodic Table!

Before we try some others lets figure out what “ide” looks like for some nonmetals

Level 1: Try a few out

NaBr

CaBr2

FrBr

MgBr2

MgCl2 K2O

Level 2: Name to Formula

Example: Sodium Chloride NaCl

Beryllium Bromide

Cesium Bromide

Sodium Fluoride

Calcium Phosphide

Lithium Chloride

Magnesium Sulfide

Level 3: Transition Metal Name

Example: Copper (III) Iodide = CuI3 Gold (VI) iodide = AuI4

Nickel (I) oxide Iron (V) fluoride

Cobalt (II) oxide Tin (III) nitride

manganese (VII) oxide niobium (V) chloride

titanium (III) phosphide palladium (IV) sulfideLevel 4: Transitions Metals Going the other direction!

Rules:1) The metal goes first 2) Second is the nonmetal + ide

Example: LiBr Lithium Bromide

Br Bromide I _____________________ O_______________________

F _______________________ N______________________ P_______________________

Cl _______________________ S _______________________ H ______________________

EXAMPLES!!Cr2O3 = Chromium (III) Oxude CuF2 = Copper (II) Fluoride

CuF PbI2 PbCl4

CrO3 AuBr NiO

Naming Covalent compounds: Prefixes: (place the following prefixes with the right number: di- , mono- , tri-, hexa, tetra, penta)1- 2- 3- 4- 5- 6- 7-

8- 9- 10-

Level 1: Match the compound with the correct name:

1) _____Carbon Dioxide 2) _____Carbon Monoxide 3) _____Sulfur Trifluoride 4) _____Nitrogen Tribromide 5) _____Nitrogen Monofluoride

A) NFB) CO2

C) SF3

D) COE) NBr3

Level 2: Write the formulas for the following covalent compounds:

1) phosphorus dibromide _______________

2) hexaboron silicide ____________________

3) chlorine dioxide _______________________

4) Nitrogen triiodide _____________________

5) hydrogen iodide ______________________

6) Diboron trisulfide ____________________

7) iodine pentafluoride _________________________

8) dinitrogen tetraoxide ________________________

Level 3: Write the names for the following covalent compounds:

9) P4S5 __________________________________

10) O2 __________________________________

11) SeF6 __________________________________

12) Si2Br6 __________________________________

13) SCl4 __________________________________

14) CH4 __________________________________

15) B2Si __________________________________

16) NF3 __________________________________

Independent Practice/Homework Name ____________________________

Rules:1) The first nonmetal 2) Second is the nonmetal + ide3) Prefixes – tell the number.4) No prefix = 1.

Example:Carbon Dioxide:

1 carbon. 2 Oxygens.

Answer = CO2

In the space provided, tell which type of bond would be formed (either covalent or ionic) between the two atoms given:1) Na & Cl _________________ 7) Zn & Cl __________________ 10) S & F _________________2) H & S __________________ 8) Ca & O __________________ 11) Cr & Cl _______________3) C & H __________________ 9) P & I __________________ 12) I & C __________________
