2
Take out a pen/pencil Three colors (crayon, colored pencils, markers)
3
On the top flap of your flip book write “Chemical Naming Flip Book” Name Period
4
Label the tabs of your flip book according to the diagram on the right. Ionic Naming Ionic Formulas Molecular Naming Molecular Formulas Polyatomic ions/Periodic Table Naming Chemical Compounds Your NamePeriod ?
5
Color 1: Shade in elements in group 1 and 2 (not hydrogen) as well as Ag, Zn, Al Color 2: Shade in the non metals (elements to the right of the stair step and hydrogen) Color 3: All other metallic elements Make the following Key at the bottom: Ionic compound, no roman numeral Ionic compound, use roman numeral Molecular compound, use prefixes
6
Group 1 = +1 Group 2 = +2 Group 8 = 0 Group 7 = -1 Group 6 = -2 Group 5 = -3 Ag +1 Zn +2 Al +3
7
Add the diatomic molecules: I 2, Br 2, Cl 2, F 2, O 2, N 2, H 2 Methane = CH 4 Ammonia = NH 3 Add Cyanide = CN - to -1 Ions
8
Step One: Name the cation and anion (in that order) Recall – Anions end in –ide unless they are polyatomic ions ex) FeCl 3 iron chloride Step Two: Figure out if you need a Roman numeral in the name. Look at the back page of your flip book and see if it needs a Roman numeral. If it is a transition metal, it probably does. Ex) Yes, this one does. Step Three: Figure out what the Roman numeral should be The charges in an ionic compound must add up to zero. Reverse the “Swap and Reduce” – but make sure the charge on the ion is correct Mathematically determine the charge Fe+?? 3 Cl -1 = -3Fe must be 3+ to make the charge add up to zero Iron (III) Chloride
9
MgBr 2 V 2 O 5 CuSO 4 Cu 2 O
10
Step One: Translate the name into the ions. Don’t skip this step. The roman numeral tells the charge of the ion for transition metals. If no charge given, use the periodic table to determine. Ex) copper (II) fluorideCu +2 F -1 Step Two: Swap and Reduce Cu +2 F -1 CuF 2 Step Three: Put parenthesis around the polyatomic ion if necessary after swapping It is needed when you swap down a number to a PAI other than 1. Ex) calcium hydroxideCa +2 OH -1 Ca(OH) 2 Step Four: Reduce if necessary Looking only at the numbers you swapped (not numbers part of the polyatomic ion), make sure they are in the lowest possible ratio. Ex) Sn 2 S 4 SnS 2 Ex) Fe 2 (SO 4 ) 2 FeSO 4
11
Prefixes 1 mono- 6 hexa- 2 di- 7 hepta- 3 tri- 8 octa- 4 tetra- 9 nona- 5 penta- 10 deca- To name a molecular compound, write two words: Prefix + Name of first nonmetal + Prefix + Name of second nonmetal + ide Exceptions: - don’t write mono- if there is only one of the first element. - don’t use the following double vowels when writing names (oa oo)
12
Cl 2 O 7 = dichlorine heptoxide CBr 4 = carbon tetrabromide
13
Use the prefixes given in the name to determine how many of each type of atom you have. Do not reduce (like ionic compounds)
14
tetraiodine nonoxide = I 4 O 9 sulfur hexafluoride = SF 6
