Question

What it the difference in electronegativiy for the most ionic of the following compounds: CsCl, MgF₂, FI, and NH₃?

Answer 1

The difference in electronegativity determines the type of bonding in a compound. Comparing the electronegativity values of the given compounds, MgF₂ has the highest electronegativity difference and the most ionic character.

Step-by-step explanation:

The difference in electronegativity affects the type of bonding in a compound. The larger the difference in electronegativity, the more ionic the bond is. By comparing the electronegativity values of the atoms in the given compounds, we can determine the compounds with the most ionic character.

1. CsCl: Electronegativity of Cs = 0.79, Electronegativity of Cl = 3.16. The electronegativity difference is 2.37.
2. MgF₂: Electronegativity of Mg = 1.31, Electronegativity of F = 3.98. The electronegativity difference is 2.67.
3. FI: Electronegativity of F = 3.98, Electronegativity of I = 2.66. The electronegativity difference is 1.32.
4. NH₃: Electronegativity of N = 3.04, Electronegativity of H = 2.20. The electronegativity difference is 0.84.

Based on these values, MgF₂ has the highest electronegativity difference and the most ionic character.
