Ionic Compounds and Transition Metals

What is a key characteristic of naming ionic compounds that contain transition metals?

• They always use prefixes to indicate the number of atoms.

• They often include Roman numerals to specify the charge of the transition metal.

• They are named by simply combining the metal and non-metal names.

• They do not require any special naming conventions.
