Answer:
0.63 is the fraction of bonding
Step-by-step explanation:
This is the formula for fraction of bonding
covalent = 1 - e ^( - 0.25 . ΔEn²)
First of all, let's determine ΔEn, where you subtract the two values of electronegativity for each element
En O = 3.5
En Ti = 1.5
ΔEn = 3.4 - 1.5 = 2
covalent = 1 - e ^( - 0.25 2²)
covalent = 1 - e ^(- 0.25 . 4)
covalent = 1 - e ^-1 → 0.63
bonding is mostly covalent
