How do you name ionic compounds?

• Name the metal

• Put parantheses with the oxidation number of the metal

  • Ignore column 1 and column 2 numbers and also ignore Al, Zn, Cd, and Ag (+3, +2, +2, +1)

• Name the non-metal with an -ide spending

How do you name molecular compounds?

• Give numerical prefix to the first element

• Name the first element by using its regulare name

• Give # prefix to second element

  • Name nonmetal using “ide”Whe
