PART 2: HOW TO NAME CHEMICALS Compounds made of nonmetals only Write the chemical that’s on the left of the P. Table first. Change the ending of the second chemical to “ide” Add prefixes (like mono-, di-, tri-) to tell how many of each atom there are.
Info! mono- means 1 di- means 2 tri- means 3 tetra- means 4 penta- means 5 hexa- means 6
More info! Why is there the extra step of using prefixes for chemicals with nonmetals only? Because unlike metal/nonmetal compounds, these can bond in more than one way: there is NO, NO2 and N2O! We need different names for them!
PART 2: HOW TO NAME CHEMICALS Compounds made of nonmetals only Yes. Step 1
Write the chemical that’s on the left of the P. Table first. Step 2
Change the ending of the second chemical to “ide” Step 3
Add prefixes (like mono-, di-, tri-) to tell how many of each atom there are.
Example: Name the chemical H2O Step 1: hydrogen oxygen Step 2: hydrogen oxide Step 3: dihydrogen monoxide
PART 2: HOW TO NAME CHEMICALS Compounds made of nonmetals only Yes. Step 1
Write the chemical that’s on the left of the P. Table first. Step 2
Change the ending of the second chemical to “ide” Step 3
Add prefixes (like mono-, di-, tri-) to tell how many of each atom there are.
Example: Name the chemical NI3 Step 1: nitrogen iodine Step 2: nitrogen iodide Step 3: nitrogen triiodide
Hint! If there is only 1 of the first element, it doesn’t need a prefix.
