Electronegativity and Bond Character Quiz

What is the range of electronegativity values across the periodic table?

• 0.5 to 4.5

• 1.0 to 3.5

• 0.7 to 4.0

• 0.0 to 5.0

How does electronegativity change across the periodic table?

• Decreases from right to left and bottom to top

• Increases from right to left and top to bottom

• Decreases from left to right and top to bottom

• Increases from left to right and bottom to top

What is the electronegativity difference range for polar covalent bonds?

• 1.7 to 3.0

• 0.4 to 1.7

• 0.0 to 0.4

• 0.0 to 1.0

In a nonpolar covalent bond, how are the electrons shared?

• Equally between atoms

• Not shared at all

• Transferred completely to one atom

• Unequally between atoms

What partial charge does chlorine acquire in a polar covalent bond with hydrogen?

• Delta minus

• Delta plus

• No charge

• Full negative charge

What happens to sodium's valence electron in an ionic bond with chlorine?

• It is shared equally

• It is shared unequally

• It is transferred to chlorine

• It remains with sodium

What is the electronegativity difference for a bond to be considered ionic?

• Between 0.4 and 1.7

• Less than 0.4

• Greater than 1.7

• Exactly 1.0

What does a 50% ionic character on the graph indicate?

• Ionic bond

• Polar covalent bond

• Nonpolar covalent bond

• Metallic bond

Why is it impossible to achieve 100% ionic character?

• Electrons are always shared equally

• Positive ions repel electrons

• Opposite charges attract electrons back

• Electrons are never transferred

What is the significance of the 0.4 electronegativity difference cutoff?

• It marks the end of ionic character

• It marks the end of polar character

• It marks the start of polar character

• It marks the start of ionic character
