Electronegativity and Ionic Compounds

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.

What type of compound is ZnF2?

• Covalent

What is the general rule for determining if a compound is ionic?

• It contains two metals.

• It contains a metal and a non-metal.

• It contains two non-metals.

• It contains a noble gas.

Where is zinc located on the periodic table?

• In the non-metal section

• In the noble gas section

• In the metal section

• In the metalloid section

What is the electronegativity of fluorine?

• 1.65

• 2.98

• 4.65

• 3.98

Why is the difference in electronegativity important in determining bond type?

• It shows the compound's solubility in water.

• It determines the melting point of the compound.
