electrons are shared between all aluminum ions in the bar
True.
The most familiar one is aluminum, which can form ions with a charge of plus 3, for example in compounds such as aluminum oxide.
There are 3 ions in the formula Al2SO4 (2 aluminum and 1 sulfate), but this formula is wrong. The formula of aluminum sulfate is Al2(SO4)3 which contains 5 ions: 2 aluminum ions and 3 sulfate ions.
When discussing ions, remember that opposites attract. Therefore, when ions bond together, you will find positive ions interacting with negative ions so the final molecule has no charge overall.
This is a levis acid.Al Shows the +3 as theoxidation number.
+3 ion
I believe that would form aluminum chloride.
Three
True.
Molecules have no net electric charge; ions do.
Yes.

calcium will give two electrons to form Ca2+ ions. oxygen will form two electrons to form O2- ions. these ions are linked (binded) together in CaO.
Aluminum has trivalent cation. It is Al3+
