Question
1. Based on the Eo values in appendix 1 at the end of your lab manual, rank each of the metals from most active to least active. include the H+ ion and Ag in your ranking.
Look up the ionization energy of each metal and list it next to the metal in your report. Please state if there us a relationship trend between metal activity and ionization energy.
The ionization energy is not the Eo value, it needs to be something else. I'm confused about what units the ionization energy is supposed to be in, and if there's any trend between ionization energy and activity. I'm pretty sure there is! Just looking at ionization energies on different websites I'm not seeing any clear relationship...unless I'm misunderstanding something here.
I kinda feel like this question is poorly worded.
Explanation / Answer
Basically you need a relation between E0, activity and ionization energy of metals.
As the chemical reactivity increases their standard reduction potential(E0) will decreases. For example, Au is a least reactive metals and it has very high reduction potential of +1.498 V. But K or potassium is a highly reactive metal and it has a reduction potential of -2.931 V.
Now, ionization energy is defined as the minimum energy required to remove an electron from its last shell or valance shell or most loosely bounded electron from a gaseous isolated neutral atom. If the activity is more it will react spontaneously, or very low attraction between nucleus and outermost electron, so it can release an electron very easily with out taking more energy. So reactive element will have very low ionization energy.
