reactivity of metal

hi there. i have four metals: Zn, Mg, Cu, and Al
I have to rank them from most reactive to least reactive.
i was wondering how would i do it.

Look at the orbitals - more complete orbitals = less reactive

reactivity of metals in greatest at the top left, decreases down, decreases to the right...

i think it would be nice to mention that is in relation to the periodic table and the placing of elements on that ;P
and i thought reactivity was greatest on the right top (Fluorine being to most reactive element because the noble gases dont react)
and least reactive were down in the bottom left (Francium being the least reactive)
maybe im wrong but im pretty sure thats how it went..

I'm pretty sure that you've got that mixed up, First. The elements in the first column of the periodic table are definitely the most reactive. They only need to loose one electron to reach the ideal arrangement, whereas elements like fluoride need to gain one--gain, not lose, so they tend to have lesser reactions.
