i. Define the term ‘electronegativity.’ ii. Explain how the concept of electronegativity relates to bond polarity.
I. Electronegativity, symbolized as χ, is the tendency of an atom to attract shared electrons to itself. An atom's electronegativity is affected by both its atomic number and the distance...
