I do not understand the question
Aluminium forms the Al3+ ion
Aluminium is a metal and one description of metal bonding is that metals are latttices of ions surrounded by electrons.
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.
There are two ions, aluminum is one ion and chloride is the other ion
electrons are shared between all aluminum ions in the bar
The formula for aluminum oxide is Al2O3, which means that, if aluminum oxide is ionically bonded, every formula mass of aluminum oxide contains three O-2 ions. In this instance, 0.65 formula masses of aluminum oxide would contain 3 X 0.65 or 1.95 moles of O2-. If aluminum oxide were covalently bonded, it would not contain any O-2 ions.
Aluminum ions carry a charge of three. Al3+.

Aluminum ions are positive, and have three neutrons in it.
Aluminum is 3+ and chloride is 1-. So, you need 3 chloride ions to neutralize 1 aluminum ion.

Aluminum has trivalent cation. It is Al3+
The formula for aluminum oxide is Al2O3, which means that, if aluminum oxide is ionically bonded, every formula mass of aluminum oxide contains three O-2 ions. In this instance, 0.65 formula masses of aluminum oxide would contain 3 X 0.65 or 1.95 moles of O2-. If aluminum oxide were covalently bonded, it would not contain any O-2 ions.
Three
Aluminum ions carry a charge of three. Al3+.
AlCl3
AlPO4
Al2O3 contains aluminum ions Al3+ and oxide ions O2-, though it is normally a solid.
