Question

Calculate the electronegativity difference between the atoms in each of thefour substances below. ***There should be NO negative values.***HBrHFНІHCI

Answer 1

In order to calculate the electronegativity of 2 elements, we need to have their individual values of electronegativity, which can be easily found in tables online the values for every element, and for the elements in our question we have:

H = 2.1

F = 4.0

Cl = 3.0

Br = 2.8

I = 2.5

Now we can find the difference of electronegativity:

HBr = 2.8 - 2.1 = 0.7

HF = 4.0 - 2.1 = 1.9

HI = 2.5 - 2.1 = 0.4

HCl = 3.0 - 2.1 = 0.9
