Define electronegativity. A neutral atom has high electronegativity. Describe what happens to this atom during ionic bond formation. (10 points)

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?

An atom of which element reacts with an atom of hydrogen to form a bond with the greatest degree of polarity ?
