1 1 Which is the best representation of the cyanate anion? And why do you think so? Formal Charge N C O -1 0 0 0 0 -1 -2 0 +1 (A) (B) (C) C O 2 The ability of an atom to attract electrons in a molecule is called electronegativity . It requires much energy to remove electrons from atoms with high ionization potentials. It requires much energy to remove electrons from anions of those atoms that have a high electron affinity. So it makes sense that atoms with high ionization potentials and high electron affinities also have high electronegativities. Guided Explorations 08-2, p 73 Electronegativity & Bond Properties
