The video tutorial explores whether ZNF2, zinc fluoride, is ionic or covalent. It begins by identifying zinc as a metal and fluorine as a non-metal on the periodic table, suggesting an ionic nature. The video further examines the electronegativity difference between zinc and fluorine, which is greater than two, confirming ZNF2 as an ionic compound. Dr. B concludes by affirming the ionic nature of zinc fluoride.
