If you are looking at the NAME of the
compound... |
| acid |
The compound name will end in the word "acid".
Examples: hydrochloric acid, sulfuric acid, permanganic acid |
| hydrate |
The compound name will end in the word "hydrate" which
will have a number prefix (like mono, di, tri, tetra, etc).
Examples: magnesium sulfate hexahydrate,
copper(II) chloride dihydrate |
| ionic compound |
The first word in the name of the compound will be the
name of a metal or else ammonium. This is because an ionic compound
consists of a cation and an anion, and the cation is always written
first. In this course, all of the cations we will see are either
metals or else ammonium. The second word in the name of the
compound could end in "ide" or "ate" or "ite". Examples: sodium
chloride, aluminum nitrate, zinc sulfate, ammonium phosphate, iron(II)
oxalate, gold(III) bromide |
| molecular compound |
The compound name will contain no metals. In
this course, all of the molecular compounds we will see contain only
nonmetals and metalloids. In addition, there will probably be
number prefixes (mono, di, tri, tetra, etc) for either the first word in
the compound name or the second word, or both. Also, the ending
the second name is always "ide". Examples: carbon dioxide,
dinitrogen pentoxide, arsenic pentafluoride, sulfur trioxide |
