Answer Posted / muhammad zohaib
Bond character can be assessed by electronegativity
difference. A 100% covalent bond will have a 0
electronegativity difference. This can be achieved with the
correct combination of atoms such as Si with
Ge or if 2 of the same atom bond together like H2. A 100%
ionic bond would be when one atom
completely takes the bonding electrons of another atom.
But, for this to occur one of the atoms would
have to have 0 ability to pull a bonded electron to itself.
This atom would have 0 electronegativity. No
atom has 0 electronegativity so a 100% ionic bond cannot
exist.
