Look at the table of electronegativities. At one end is gold and platinum, you see those all the time, they're always shiny, you'll often see copper and iron around as well, often, not as shiny. Look at the other end, metals like sodium and potassium, you don't see those lying around often, do you? Where do copper and magnesium fit in the sequence? And what are they closer to?
by the way im 15 so ive not bein doing chemistry long lol
Not to worry, the laws of chemistry remain the same no matter how old you are.
Mg is 1,83 and Cu is 1,65 what ever that means lol (im trying here)
im sorry i dont get the electronegativity but what i do know is the electron from the Mg go to the Cu because the Mg is higher in the E.C.S so does Cu (II) become Cu(IIII) <<< i think thats impossible but im just guessin here
Nope, that's not what happens, but you're trying. Read up a bit, and then come on back with some other theories.
