Ionic Compounds
Ion: Any atom that has a charge
Cation:An ion with a + charge
anion:
An ion with a - charge
![Page 3: Ionic Compounds. Ion:Any atom that has a charge Cation: An ion with a + charge anion: An ion with a - charge](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ebc5503460f94bc4eec/html5/thumbnails/3.jpg)
Ionic BondsA bond that forms between
(+) metals and (-) non metals.
Electrons are transferred and then the opposite
charges attract.

Octet RuleElement always move to
become more stable. Most elements change their
electron configuration to match the configuration of
noble gasses.
Elements want 8 valence electrons

Rules for Naming Ionic Compounds
1. The first element (metal) name does not change.2. The second elements name ending changes to -ide
NaO
MgCl2
Al2S3

Rules for Naming Ionic Compounds
(except for polyatomic ions, use the name on the chart)
SO42- = sulfate
Na2SO4 = sodium sulfate

Rules for Naming Ionic Compounds
3. If it is a transition metal Roman Numerals must be used.FeCl FeCl2 FeCl
3The Roman numeral tells you the charge of the transition metal

Rules for Naming Ionic Compounds
4. There are no prefixes in ionic compounds

Rules for Writing Ionic Compounds
1.Charge must always cancel out
+ and – charges add up to zero.2. Find the charges from the periodic table or the chart.

Rules for Writing Ionic Compounds
3.If the charges are the same they cancel out and it is a one to one ratio.
Ca2+ , O2- Ca1O1

Rules for Writing Ionic Compounds
4.If the charges are not the same then use the cross rule
Ca2+ Cl1-
Ca1Cl2
