HOW TO NAME CHEMICALS Hint! If a chemical has more than two types of atoms, you’ll need to remember the names of the polyatomic groups!! Remember, you memorized some common polyatomic groups on the Reactions 1 playlist! Bonus Hint! If a chemical has polyatomic groups, treat it as a chemical made of both metals & nonmetals, whether it actually is or not!
Compounds made of both metals & nonmetals Write the chemical that’s on the left of the P. Table first.
More than two types of atoms?
Change the ending of the second chemical to “ide”
Write the chemical that’s on the left of the P. Table first. Look on a “Polyatomic Groups” chart to find the name of the polyatomic roup.
PART 2: HOW TO NAME CHEMICALS Compounds made of both metals & nonmetals
Example: Name the chemical NaF Step 1: sodium fluorine Step 2: sodium fluoride
Step 1
Write the chemical that’s on the left of the P. Table first.
More than two types of atoms?
Step 2
Change the ending of the second chemical to “ide”
Write the chemical that’s on the left of the P. Table first. Look on a “Polyatomic Groups” chart to find the name of the polyatomic roup.
PART 2: HOW TO NAME CHEMICALS Compounds made of both metals & nonmetals
Example: Name the chemical CaBr2 Step 1: calcium bromine Step 2: calcium bromide
Step 1
Write the chemical that’s on the left of the P. Table first.
More than two types of atoms?
Step 2
Change the ending of the second chemical to “ide”
Write the chemical that’s on the left of the P. Table first. Look on a “Polyatomic Groups” chart to find the name of the polyatomic roup.
PART 2: HOW TO NAME CHEMICALS
Example: Name the chemical Na2O Step 1: sodium oxygen Step 2: sodium oxide
Compounds made of both metals & nonmetals Step 1
Write the chemical that’s on the left of the P. Table first.
More than two types of atoms?
Step 2
Change the ending of the second chemical to “ide”
Write the chemical that’s on the left of the P. Table first. Look on a “Polyatomic Groups” chart to find the name of the polyatomic roup.
PART 2: HOW TO NAME CHEMICALS • Examples
“-ide”
of common elements with their endings changed to
→ chloride • fluorine → fluoride • oxygen → oxide • nitrogen → nitride • sulfur → sulfide • bromine → bromide • iodine → iodide • chlorine
