1. Look up Electronegativity Values:
* Sodium (Na): Electronegativity = 0.93
* Bromine (Br): Electronegativity = 2.96
2. Calculate the Difference:
* Difference = Electronegativity of Br - Electronegativity of Na
* Difference = 2.96 - 0.93 = 2.03
Conclusion:
The difference in electronegativity values between sodium and bromine is 2.03. This significant difference indicates that bromine is much more electronegative than sodium. This means that in a bond between sodium and bromine (like in sodium bromide, NaBr), bromine will have a stronger pull on the shared electrons, resulting in a polar covalent bond.
