The ionization energy of an alkali metal is reflected in its reaction with water, where a bigger explosion indicates an easier reaction. In general, if X is an alkali metal, the reaction with water is: X (s) + H2O (l) = XOH (aq) + H2 (g). How does the reaction relate to the ionization of X? Write the reaction for X in the boxes below. This reaction does not need to be balanced. Any other species and the state of the reactants and products can be ignored. Include the formal charge in the superscript box. If there is no formal charge, write "0".
17) The first three ionization energy of an element X are 590, 1145, and 4912 kJ•mol^-1. What is the most likely formula for the stable ion of X?
