Study Notes

Electronegativity

Electronegativity (χ) is the tendency of an atom to attract shared electrons when forming a chemical bond.
It is affected by both atomic number and the distance of valence electrons from the charged nucleus.
Higher electronegativity means an atom or substituent group attracts electrons more.
Electronegativity helps estimate bond energy and chemical polarity, ranging from covalent to ionic bonding.
Electropositivity is the opposite of electronegativity, characterizing an element's tendency to donate valence electrons.
Nuclear charge (number of protons) and the number and location of outermost electrons determine electronegativity.
