Naming and Properties of Ionic Compounds

The video tutorial explains how to name the compound BaI2, known as barium iodide. It begins by identifying barium as a metal and iodine as a non-metal, classifying BaI2 as an ionic compound. The tutorial details the naming process, changing 'iodine' to 'iodide' to form 'barium iodide'. It also covers deriving the formula, explaining that barium has a 2+ charge and iodine a 1- charge, requiring two iodine atoms to balance one barium atom, resulting in the formula BaI2.

• It is changed to -ate

• It is changed to -ide

What is the charge of barium in the compound BaI2?

• 2-

• 1-

• 2+

• 1+

Why do we need two iodine ions to balance one barium ion in BaI2?

• Because iodine has a 1- charge

• Because barium has a 1+ charge

• Because barium has a 1- charge

• Because iodine has a 2+ charge
