Verified step by step guidance1
Identify the electronegativity values of sodium (Na) and chlorine (Cl) on the Pauling scale. These values are typically found in a reference table.
Recall that the electronegativity difference between two elements is calculated by subtracting the smaller electronegativity value from the larger one.
Write the formula for the electronegativity difference: \(\Delta EN = |EN_{Cl} - EN_{Na}|\) where \(EN\) represents electronegativity.
Substitute the known electronegativity values of sodium and chlorine into the formula.
Calculate the absolute difference to find the electronegativity difference between sodium and chlorine.
