Major Points:
There are two types of compounds:
1. a compound can contain a metal and a nonmetal
2. a compound can contain 2 nonmetals
Binary ionic compound
- These compounds contain positive ion(cation) and a negative ion(anion)
Two types of Ionic Compounds:
Type 1- the metal will only have one charge
Type 2- the metal can form two or more cation that have different charges
Type 3- a bond between two non-metals
Rules for naming Type 1:
- 1. The cation is always be named first and the anion named second
- - Cation will have the same name as the element
- - Anion will have an ide ending.
- - There some exceptions with polyatomic ions
- Rules for naming Type 2:
- - Metal name(roman numeral) Anion name
- - Example Iron(II)oxide
- Rules for naming Type 3:
- - These Compounds contain 2 or more nonmetals that are covalently bonded.
- Acids:
- - Acids can be initially described as molecules that will release one or more H+ when attached to an anion.
