Non-Binary nomenclature – Flashcards

Lead II dichromate

In this example, lead has an unusual valence of II instead of the expected valence of IV.  Therefore, you must indicate the change with a roman numeral in the name...

Ni(CN)₂ 

don't forget the ( ) around the ;CN;

Copper II carbonate

(must have a roman numeral in the name)

Chromium III phosphate

;

(must have a roman numeral in the name)

Silver carbonate;

or;

Silver I carbonate

;

(The valence of Silver is always I so you don't need a roman numeral in the name this time...)

Mercury II sulfide (a binary compound)

(must have a roman numeral in the name)

Magnesium bicarbonate

or

Magnesium hydrogen carbonate

Mercury I iodide

(you need a roman numeral in the name here)

Ni(CN)₂

(don't forget the paranthesis in this formula!!!)

Cobalt II sulfate

(you need a roman numeral in the name here)

Nickel II chromate

(you need a roman numeral in the name here)

Ca(OH)₂

don't forget the ( ) around the OH

Mercury I bicarbonate

or

Mercury I hydrogen carbonate

(the valence of Mercury is I in this example)

_{Manganese II sulfate}

Ni(OH)₃

_{remember you need () around the hydroxide!!!}

_{Nickel I nitrate}

ammonium chloride

Potassium permanganate

Mercury II thiosulfate

Must have the roman numeral in the name since Mercury is a transition element of multi valence.
