Names Of Compounds/ Things Flashcards
Water
H2O
Ammonia
NH3
Why would the name end in -ide?
If there are only 2 elements present
Ending for hydroxides
-OH
Ending for cyanides
-CN
Why do we use Roman numerals in brackets
If the element has more than one oxidation state we show the charge of the element in Roman numerals e.g. Iron(II) chloride = FeCl2 and Iron(III) chloride = FeCl3
What happens when there are 2 non metals
The actual number of the atoms in the element present are stated e.g. CO = Carbon Monoxide
CO2 = Carbon Dioxide
SO2 = Sulfur Dioxide. It could be called Sulfur(IV) Oxide because Oxygen is diatomic and so the Roman numerals go up in 2s
Carry on the pattern - 1 = mon-
2= di- 3= tri- 4= tetra- 5= penta- 6= hexa- 7= hepta- 8= octa- 9= nona- 10= deca-
