Answer:

[tex]0.08875[/tex]

Explanation:

Hello,

In this case, the first step is to compute the difference in the electronegativity for the formed bond between gallium and phosphorous by:

[tex]\Delta E=2.1-1.6\\\\\Delta E=0.5[/tex]

Thus, we can compute the percentage of ionic character by:

[tex]\%\ ionic\ character=16\Delta E +3.5 (\Delta E)^2\\\\\%\ ionic\ character=16*0.5+3.5*0.5^2\\\\\%\ ionic\ character=8.875\%[/tex]

So the fraction is just:

[tex]\frac{8.875}{100}=0.08875[/tex]

Which has sense since gallium phosphide is a non-polar compound.

Regards.
