netineya [11]

Answer:

0.086

Explanation:

The formula for calculating the fraction of a covalent bond can be expressed as:

= exp (-0.25ΔE²)

= exp[-0.25(E_{Al}-E_{p})^2]---(1)

from the equation above;

E_{Al} = the electronegativity of aluminum

E_P = electronegativity of phosphorus

Using the data from periodic table figures;

E_{Al} = 1.5

E_P = 2.1

∴

fraction of the covalent = exp[-0.25(1.5 - 2.1)²]

fraction of the covalent = exp(-0.09)

fraction of the covalent = 0.914

Now, the fraction of ionic bond will be = 1 - the fraction  of covalent bond

= 1 - 0.914

∴

the fraction of bond that is ionic = 0.086
