= Naming =
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
== Naming acids ==
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
