Steps to NAMING ionic compound:1. Name the cation2. Name the anion and change the ending to “ide”
- Group 17: ine ide- Oxide- Sulfide- Selenide- Phosphide- Silicide- nitride- hydride
3. Add (roman numeral) if the cation is a transition metal
1. Calcium and Bromine 2. MgS
Naming Ionic Compounds
Examples:
Steps:1. Name the cation2. Name the anion and change the
ending to “ide”- Group 17: ine ide- Oxide- Sulfide- Selenide- Phosphide
3. Add (roman numeral) if transition metal
1. FeO 2. CrBr3
Naming Ionic Compoundsw/ Transitional Metals
Examples:
Steps:1. Name the cation2. Name the anion and change the
ending to “ide”- Group 17: ine ide- Oxide- Sulfide- Selenide- Phosphide
3. Add (roman numeral) if transition metal
**Work Backwards**
Steps to NAME an ionic compound with Polyatomic Ions:
1. Name cation (or ammonium only “+” p.i.)2. Name polyatomic ion
*** DO NOT CHANGE ANYTHING***
Example: Mg(NO3)2
Molecular / Covalent Compounds
• A compound that is composed of 2 or more non-metals
• How to recognize an molecular/covalent compound …
• Anion and anion• Nonmetal and nonmetal• - and -
Steps to NAMING a covalent compound :
1. Name the first element in formula2. Name second element in the formula and change
endings to “ide”3. Add prefixes before each element name (according
to the subscripts)4. EXCEPTION never use mono for the 1st element
1. CO2 2.N3F8
Naming Covalent CompoundsExamples:
Steps:1. Name first element in
formula2. Name second element and
change endings to “ide”3. Add prefixes (according to
how many there are)4. EXCEPTION never use
mono for the 1st element
Steps to Write the Formula for a covalent compound :
1. Write the symbol for the first element in the compound. 2. Write the formula for the second element in the formula.3. Add the prefixes as subscripts for each element.
• NO REDUCING• NO CHARGES
Ex 1: Carbon Monoxide Ex 2: Diphosphorus tetrachloride
