The video explores whether ridium fluoride (RBF) is ionic or covalent. It concludes that RBF is ionic by analyzing its components on the periodic table, identifying ridium as a metal and fluorine as a non-metal. The video further examines the electronegativity difference between ridium and fluorine, which is greater than three, confirming the ionic nature of RBF.
