The electron configuration of an atom determines how much energy is involved in its reactions. The table shows how some elements in the same amounts react with water. Alkali Reactions with Water Element - Reaction with Water Li (Lithium) - oxidizes; heat produced Na (Sodium) - oxidizes; heat and smoke produced K (Potassium) oxidizes; heat, smoke, and flames produced Which reaction would MOST likely occur when rubidium (Rb) is placed in water? A oxidizes slightly B oxidizes; produces more heat, smoke, and flames than potassium (K) C oxidizes; produces more heat and smoke than sodium (Na) D oxidizes; produces more heat than lithium (Li)
