Element naming is a nightmare
|
|
|
|
|
|
|
|
|
|
Prefixes are standard before multiple of a molecule
|
|
|
|
|
|
|
|
|
|
* Write element furthest left on table first
|
|
|
|
|
* write element furthest right on table second
|
|
|
|
|
* Full element name for first element and first syllable of second element with
|
|
|
|
|
the +ide ending
|
|
|
|
|
* Use latin prefixes to indicate the number of atoms of each element (only use
|
|
|
|
|
mono on second element)
|
|
|

== Ion naming ==
|
|
|
|
|
|
|
|
|
|
* Cations
|
|
|
|
|
* Element name + ion
|
|
|
|
|
- K+ = potasium ion
|
|
|
|
|
* Transition elements (variable charge)
|
|
|
|
|
- Element name + (roman numeral) + ion
|
|
|
|
|
- Fe^3+ = iron(III)ion
|
|
|
|
|
- Fe^2+ = iron(II)ion
|
|
|
|
|
|
|
|
|
|
* Anion
|
|
|
|
|
- Replace ending of element with -ide ion
|
|
|
|
|
- F^- = fluoride ion
|
|
|
|
|
- N^3- = nitride ion
|
|
|
|
|

|
|
Naming compounds of ions
|
|
|
|
|
|
|
|
|
|
* Name = cation + anion
|
|
|
|
|
- MgO = magnesium oxide
|
|
|
|
|
- Fe,,2,,(CO,,3,,),,3,, = iron(III)carbonate ferric carbonate

See [[acids]]
|
|
|
|
|
|
|
|
|
|
* Named based on anion attached to the hydrogen
|
|
|
|
|
* When binary acid (one ion with hydrogen)
|
|
|
|
|
- Prefix -hydro
|
|
|
|
|
- first syllable of anion
|
|
|
|
|
- suffic -ic
|
|
|
|
|
* Complex acids have Oxygen in them
|
|
|
|
|
* Acid with polyatomic ion (OH), (NO,,3,,)
|
|
|
|
|
- replace -ate with -ic
|
|
|
|
|
* Polyatomic with one extra oxygen (compared to typical polyatomic ion)
|
|
|
|
|
- prefix per-
|
|
|
|
|
- suffic -ic
|
|
|
|
|
* Polyatomic ions with one fewer oxygen (compared to typical)
|
|
|
|
|
- suffix -ous
|
|
|
|
|
* Polyatmoic ions with two fewer oxygen
|
|
|
|
|
- prefix hypo-
|
|
|
|
|
- suffix -ous
