Chapter 2 - Naming

Question 1

What are the rules for Binary ionic compounds?

Answer 1

They are held together through opposite charges on the individual ions.

1. Always put positive ion (the metal) first
2. Name the positive ion (cation)
3. For the Negative ion (anion), add “-ide” to the root of the name.

Question 2

What are the rules for binary ionic compounds containing metals having more than one common charge?

Answer 2

1. Always put the positivley charged ion (the metal) first.
2. Name the positive ion.
3. Find the charge of the positive ion (remember that the salt is neutral, so positive and negative charges must cancel out.)
4. Place it in parenthesis after the metal, using roman numerals.
5. For the negative ion,add “-ide” to the root of the name.

Ex. CuCl: Copper (I) Chloride
CuCl2: Copper (II) Chloride.
