Ionic Compounds and Electronegativity

The video tutorial explores whether Ridium Chloride (RbCl) is ionic or covalent. It begins by identifying Ridium as a metal and Chlorine as a non-metal using the periodic table, suggesting an ionic compound. The video then calculates the electronegativity difference between Ridium and Chlorine, which is greater than 2.0, confirming the ionic nature of Ridium Chloride. Dr. B concludes that RbCl is indeed ionic.

What type of compound is RbCl?

• Ionic
