Electronegativity and Bond Character Quiz

What is the range of electronegativity values across elements?

• 1.0 to 3.5

• 0.7 to 4.0

• 0.0 to 5.0

• 0.5 to 4.5

How does electronegativity change across the periodic table?

• Decreases from left to right and bottom to top

• Increases from left to right and top to bottom

• Decreases from top to bottom and right to left

• Increases from bottom to top and left to right

What type of bond is formed when the electronegativity difference is between 0.4 and 1.7?

• Ionic

• Nonpolar covalent

• Metallic

• Polar covalent

In a nonpolar covalent bond, how are electrons shared?

• Not shared at all

• Unequally between atoms

• Transferred completely

• Equally between atoms

What is the electronegativity difference for a polar bond between hydrogen and chlorine?

• 0.4

• 1.2

• 0.8

• 1.7

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

• It remains with sodium

• It is shared unequally

• It is shared equally

• It is transferred to chlorine

What is the significance of a 1.7 electronegativity difference?

• It signifies a complete electron transfer

• It indicates a 50% ionic character

• It marks the start of nonpolar character

• It shows equal sharing of electrons

Why can't a bond be 100% ionic?

• Because the positive ion repels electrons

• Because the positive ion attracts electrons back

• Because electrons are never transferred

• Because electrons are always shared equally

What does a zero percent ionic character indicate?

• Unequal sharing of electrons

• Equal sharing of electrons

• No electron sharing

• Complete electron transfer

What is the macro property significance of a 0.4 electronegativity difference?

• It marks the start of ionic character

• It indicates a nonpolar bond

• It signifies the appearance of polarity

• It shows complete electron transfer
