CHEMISTRY EXAM TOMORROW help!?

i know that you can find out if a bond is ionic/polar/nonpolar by knowing the electronegativity (subtracting smaller from larger) and i know the electronegativity trend but how do you know or find out the electronegativity numbers to subtract them to find out?HELP

Answer:

I use PCB etchant to remove the aluminum coating from my telescope mirrorA short soak at room temperatureMy guess is that if the aluminum is cleaned with steel wool or some other mild abrasive that you might have success with etching aluminumTry it.
