Question

HELPP ANSWERSSS!!!!

A student designs an investigation to test the reactivity of two elements with HCl 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?

A.
Al, because it has the higher ionization energy and more readily accepts electrons to participate in a reaction.

B.
Al, because it has the lower ionization energy and more readily gives up valence electrons to participate in a reaction.

C.
Cs, because it has the lower ionization energy and more easily gives up its valence electrons to participate in a reaction.

D.
Cs, because it has the higher ionization energy and more easily gives up its valence electrons to participate in a reaction.

Answer 1

C. Cs, because it has the lower ionization energy and more easily gives up its valence electrons to participate in a reaction.

Step-by-step explanation:

The Cs will produce the most hydrogen gas because it has a lower ionization energy and more easily gives up its valence electrons to participate in the reaction.

• Ionization energy is the energy required to remove the most loosely held electrons in an atom.
• Atoms with lower ionization energy readily goes into reactions.
• This is because they will present little barrier for the reaction to occur.
