Solution
The statement C is not correct. The electronegativity of an atom does not depend upon the atoms bonded to it. Electronegativity is a property of an atom, more specifically, it's a measure of the tendency of an atom to attract a bonding pair of electrons. It is determined by factors like the atom's nuclear charge and the number/location of other electrons present in the atomic shells. The type of atoms that are bonded to it does not affect an atom's electronegativity.
