Electronegativity of Al is approximately equal to that of
Correct answer: B. Be
- A. B
- B. Be
- C. Mg
- D. Na
Explanation
The correct answers are Be (Beryllium) and Mg (Magnesium) as they both have electronegativity values that are approximately equal to that of Al (Aluminum). The electronegativity of Aluminum is around 1.61, while Beryllium is about 1.57 and Magnesium about 1.31, making them close in value. B (Boron) is incorrect because it has a higher electronegativity of approximately 2.04. Na (Sodium) is also incorrect as it has a lower electronegativity of around 0.93, which is significantly lower than that of Aluminum.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
