The compound gallium phosphide () is a compound semiconductor having mixed ionic and covalent bonding. The electronegativities for and are 1.6 and 2.1 respectively. Calculate the fraction of the bonding that is ionic.

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:

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

So the fraction is just:

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

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
