Read each question carefully and provide your best answer. For multiple-choice questions, circle the letter corresponding to your chosen answer.
1. Which of the following elements has the highest electronegativity?
Sodium (Na)
Fluorine (F)
Carbon (C)
Oxygen (O)
2. What is the general trend of electronegativity across a period in the periodic table?
Decreases
Increases
Remains constant
Varies unpredictably
1. Electronegativity is a measure of an atom's ability to attract in a chemical bond.
2. The most electronegative element on the periodic table is .
3. A large difference in electronegativity between two bonding atoms typically results in a bond.
1. Electronegativity generally decreases down a group in the periodic table.
True
False
2. Nonpolar covalent bonds occur when there is a significant difference in electronegativity between the bonded atoms.
True
False
1. Explain why noble gases are generally not assigned electronegativity values.
Match the type of bond with its characteristic electronegativity difference.
1. Ionic bond
a. Small difference (~0-0.4)
2. Polar covalent bond
b. Large difference (>1.7)
3. Nonpolar covalent bond
c. Intermediate difference (0.4-1.7)
