A student designs an investigation to test the reactivity of two elements with HCI
to produce hydrogen gas. Using the periodic table as a model, which of the
following would you expect to produce the most hydrogen gas within the first
minute of the reaction?
2Cs (s) + 2HCl(aq) -- 2CsCl (aq) + H2(8)
2Al(s) + 6HCl(aq) -- AICI, (aq) + 3H2 (8)
Cs, because it has the lower lonization energy and more easily gives up its
valence electrons to participate in a reaction
Al, because it has the higher lonization energy and more readily accepts
electrons to participate in a reaction
Cs, because it has the higher lonization energy and more easily gives up its
valence electrons to participate in a reaction
Al, because it has the lower ionization energy and more readily gives up valence
electrons to participate in a reaction
