Al3+
Al3-
Here is the equation - Al3+ + 3e- -> Al
Aluminum's atomic symbol: Al Aluminum's ionic symbol: Al3+
Aluminum's, or Al's, atomic number is 13. Therefore, an electrically neutral aluminum atom would have 13 protons and 13 electrons. However, Al3+ has 3 less electrons than neutral aluminum, an thus only has 10 electrons.
13 in the neutral atom, 10 in the Al3+ ion
Aluminum loses 3 electrons. Since electrons have a negative charge losing them would make the aluminum atom lessnegative, which is positive. Hence, Al+3

Aluminum has trivalent cation. It is Al3+
Here is the equation - Al3+ + 3e- -> Al
The formula for aluminum oxide is Al2O3: Molar mass =581.77g/mol Al2O3.In one mole Al2O3, there are two moles of Al3+ ions, therefore 2 moles Al3+ x 26.982g/mol Al3+ = 53.964g Al3+ in one mole of Al2O3.GIVEN: mass of Al3+ = 53.964 g Al3+;Molar mass of Al2O3 = 581.77 g Al2O3UNKNOWN: % Al3+EQUATION:% Al3+...=...g Al3+x 100...g Al2O3% Al3+...=...53.964g Al3+x100......=...9.2758% Al3+581.77g Al2O3
Aluminum ions carry a charge of three. Al3+.
