Answer:
Covalent bonding is usually exhibited when the electronegativity difference between two atoms is 1.1
Explanation:
The electronegativity difference identifies the type of bonding (i.e. covalent bonding and ionic bonding) between two atoms.
Covalent Bonding is the type of chemical bonding that form by the sharing of electron pairs between two atoms.
Ionic Bonding is the type of chemical bonding that form by the complete valence electrons transfer between two atoms.
Electronegativity is the force with which an atom attract shared pair of electrons towards itself.
The formation of covalent bond occurs when the electronegativity difference (ΔEN) between two atoms, sharing electrons with each other, is less than 1.7 which means that the atoms, having covalent bonding, do not have strength to transfer electrons towards themselves. If the electronegativity is greater than 1.7 then ionic bonding exist between two atoms because they have enough strength to transfer electrons towards themselves.
