Transcript of Starts with Metal
Starts with Metal
1) Write the name of the 1st element
2) Write the name of the 2nd element, change the
ending to -ide
2) Write the name of the polyatomic ion
Do reverse criss-cross to determine charge, use a Roman numeral after the
cation
Starts with Non-Metal
1st element- Change subscript into prefix then write element
2nd element- change subscript into prefix,
write element, change ending to -
ide
Starts with H
yes
Compound is IONIC Compound is COVALENT
If 1st element is a transition metal
if anion is an ELEMENT
if anion is a POLYATOMIC ION
yes
Compound is an ACIDIs OXYGEN present?
yes
noHydro + root + -ic
acid
If polyatomic ion ends in -ite:
Root + -ous Acid
If polyatomic ion ends in -ate:
Root + -ic Acid
Don’t use Don’t use mono on mono on

Does name have a prefix or start with a non-metal?
Write elementsChange prefixes into
subscripts
DO NOT REDUCEDO NOT CRISS-CROSS
Is compound an Acid?
Does name start with hydro-?
Write symbol and charge for H and element
Do Criss-cross
Is 1st element a metal?
yes
Compound is COVALENT Compound is an ACID
yes
Compound is IONIC
yes
If root ends in -ous:use -ite polyatomic ion
If root ends in -ic:use -ate polyatomic ion
yes no
Name to FormulaXray Yellow XY
Pre-fixesmono-1di-2tri-3tetra-4penta-5
yes
Write symbol and charge for H and polyatomic ion
Do Criss-cross
Is there a Roman numeral?
Roman numeral tells you the charge
Write symbol and charge for cation and
anion
Do criss-cross
-ide = element-ide = element
-ite-ate= polyatomic ion
