Use your knowledge and electronegativity sheet to predict what the following compound is classified as.

• polar covalent

• nonpolar covalent

• ionic

• metallic

Use your knowledge and electronegativity sheet to predict what the following compound is classified as.

• nonpolar covalent

• polar covalent

• ionic

• metallic

Use your knowledge and electronegativity sheet to predict what type of bond would form between phosphorus and fluorine.

• non-polar covalent

• polar covalent

• ionic

• metallic

In a polar covalent bond, electrons are shared:

• equally

• unequally

• between two metals

• between a metal and a non-metal

The most electronegative atom in the periodic table is:

• Fluorine
• Helium
• Neon
• Francium

In this Lewis structure, the symbol above F means...

• electrons are being transferred to Fluorine
• electrons are less attracted to F than H
• electrons are more attracted to F than H
• Fluorine has formed a cation

When you are asked to find bond polarity, you should compare electronegativity values of each bonding atom to the central atom.

• true

• false

The electronegativity difference in the bonds of CH₄ is:

• 0.4

• 5.9

• -0.4

• 1.7

The electronegativity difference in the bonds of CCl₄ (carbon tetrachloride) is:

• 0.4

• 0.5

• 9.5

• 5.5
