Criss Cross Method Naming Rules

Back to

Ionic

The compound needs to be stable!

When you put the ions together, the overall charge still needs to equal zero. You write the cation (positve ion)

first, including its charge. Next, you write the anion (negative ion) including its charge. You “criss cross” the charges to form subscripts on the opposite ions!

CRISS CROSS METHOD

GO BACK

You need to write the cation first (Refer to Periodic Table for its name). If the cation is a metal that

contains multiple charges, you have to specify the charge. You do this by writing the number as a Roman Numeral in parenthesis after the

cation.Next, write the anion (Refer to Periodic Table for its

name). Drop the ending, and add the sufix –ide. If there is a polyatomic ion present, refer to

polyatomic ion sheet for its name.

Naming Rules

Back to

Main

First, the cation (positive ion) should be named. Do not cut off any parts of the

element’s name. If there is a subscript of 2 or more, see Prefix Chart

Next, the anion (negative ion) should be named.

If the element begins with a vowel, the (a) and (o) are dropped from the end of the prefix

If there is a subscript of 2 or more, see Prefix Chart

NAMING RULES FOR COVALENT BONDS

Prefix Chart

Place prefix in front of the hydrate (water molecule)

For the cat ion, just p lace the appropr iate prefix (DO NOT use mono- even i f there is a subscr ipt o f 1)

For the anion, p lace the appropr iate prefix in f ront o f the element name.
