Chemical hardness (n) measures the resistance of an atom to a charge transfer [39], chemical hardness, chemical potential (u) and electronegativity (X) can be calculated with the help of the following equations from EHOMO and ELUMO [16]:
By assuming the carbonyl group as the proton receptor, it must be worthy to notice that the resulting atomic electronegativity encompasses this functional group not singly but wholly (C=O).
The absolute electronegativity ([chi]) and global electrophilicity ([omega]) of BFC were 0.0454 and 0.2094 which indicated the stability and reactivity of inhibitor molecule.
This is in line with the case of Cu doping and supports our hypothesis that the electronegativity of the foreign elements is the key factor.
Hydrogen bonds contribute to contact angle changes, and they are formed by the high electronegativity in oxygen with the more positive hydrogen.

We can expect here weak hydrogen bonds which are formed when the hydrogen atom is covalently bonded to a slightly more electronegative atom relative to hydrogen; the electronegativity of carbon of 2.55 is only slightly higher than that of hydrogen, that is, 2.20, according to the Pauling electronegativity scale.
DFT [22] has been found to be successful in providing theoretical insights into the chemical reactivity and selectivity, using chemical concepts such as electronegativity ([chi]), hardness ([eta]), softness (S), electrophilicity index ([omega]), and local reactivity descriptors including Fukui functions f(r) and the local softness s(r).
Antibacterial activities of 2a-c increased with the decrease in electronegativity of substituent on chalcone.
Fluoride ion sensing is highly challenging due to the high electronegativity of fluorine and its small size.
