PART 2: HOW TO NAME CHEMICALS Compounds made of both metals & nonmetals Does it have a transition metal? Draw it! Write the chemical that’s on the left of the P. Table first. Change the ending of the second chemical to “ide” Show how many bonds the metal is making with (Roman Numerals)
Info! You have to draw it first, to know how many bonds the transition metal is making! Info! Roman numeral: I means 1 II means 2 III means 3 IV means 4 V means 5 VI means 6
PART 2: HOW TO NAME CHEMICALS Compounds made of both metals & nonmetals Does it have a transition metal? Step 1
Draw it!
Step 2
Write the chemical that’s on the left of the P. Table first. Step 3
Change the ending of the second chemical to “ide” Step 4
Show how many bonds the metal is making with (Roman Numerals)
Example: What is the name of CuF2? Step 1: Draw it. From the periodic table, F makes 1 bond, so it must be: F
Cu
F
Step 2: copper fluorine Step 3: copper fluoride Step 4: copper (II) fluoride
PART 2: HOW TO NAME CHEMICALS Compounds made of both metals & nonmetals Does it have a transition metal? Step 1
Draw it!
Example: What is the name of MnO? Step 1: Draw it. From the periodic table, O makes 2 bonds, so it must be:
Step 2
Write the chemical that’s on the left of the P. Table first. Step 3
Change the ending of the second chemical to “ide”
Mn
O
Step 2: manganese oxygen Step 3: manganese oxide Step 4: manganese (II) oxide
Step 4
Show how many bonds the metal is making with (Roman Numerals)
Hint! This is why you need to draw! You can’t tell how many bonds it’s making just by looking at the formula!
PART 2: HOW TO NAME CHEMICALS Compounds made of both metals & nonmetals Does it have a transition metal? Step 1
Draw it!
Example: What is the name of Au2S? Step 1: Draw it. From the periodic table, S makes 2 bonds, so it must be:
Step 2
Write the chemical that’s on the left of the P. Table first. Step 3
Change the ending of the second chemical to “ide”
Au
S
Au
Step 2: gold sulfur Step 3: gold sulfide Step 4: gold (I) sulfide
Step 4
Show how many bonds the metal is making with (Roman Numerals)
Hint! The Roman Numeral does not tell how many gold atoms are in the chemical. It tells how many bonds the gold atoms are making!
PART 2: HOW TO NAME CHEMICALS Compounds made of both metals & nonmetals Does it have a transition metal? Step 1
Draw it!
Example: What is the name of AuSO4? Step 1: Draw it. You know that SO4 makes 2 bonds:
Step 2
Write the chemical that’s on the left of the P. Table first. Step 3
Change the ending of the second chemical to “ide”
SO4
Au
Step 2: gold sulfate Step 3: gold sulfate Step 4: gold (II) sulfate
Step 4
Show how many bonds the metal is making with (Roman Numerals)
Hint! Don’t forget about polyatomic groups!
