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.
