Naming and Charges of Compounds

The video tutorial explains how to name the compound COF3. It begins by identifying cobalt as a transition metal and fluorine as a non-metal. The process involves writing the names as they appear on the periodic table, modifying the non-metal's name, and determining the charge of cobalt. The final name, 'cobalt(III) fluoride', reflects the charge of the transition metal.

What is the first step in naming the compound COF3?

• Replace the ending of the non-metal with 'ide'

• Determine the number of non-metal atoms

• Write the name of the metal as it appears on the periodic table

• Identify the charge of the metal

Which element is identified as a transition metal in COF3?

• Fluorine

• Oxygen

• Cobalt

• Carbon

How is the name of the non-metal modified when naming COF3?

• Add 'ate' to the end
