Yes - Al -----> Al3+ is the cation.
what is the cation for Ca(ClO4)2
Aluminum typically loses 3 electrons to form a 3+ cation.
Aluminum forms a cation with a 3+ charge, and the formula Al3+.
Aluminium lose 3 electrons and form the cation Al3+.
The newly formed aluminum compound in this reaction will be aluminum nitrate, since aluminum (III) cation from aluminum chloride will replace the ammonium (NH4+) cation from ammonium nitrate to form aluminum nitrate (Al(NO3)3).
Aluminium cation is 3+; bromide anion is Br-. The aluminium bromide is AlBr3.
Aluminum forms a cation of +3 charge. Sulfite is an anion of -2 charge. To combine, the two would forum aluminum sulfite of the form Al2(SO3)3.
Aluminum has trivalent cation. It is Al3+
Al2O3 - aluminum oxide (dialuminium trioxide); this oxide is not a cation or anion but a chemical molecular substance.
Aluminium, like most metals, forms cations easier than it does anions. The most common for aluminum is Al3+, when it has lost three electrons.
When aluminum forms an ionic compound, it tends to take the form of a cation with a +3 charge. This would happen because it would donate three of its electrons to the anion(s) it forms the ionic compound with.
The name for AlCl3 in the ionic form is aluminum chloride. It typically forms ionic compounds with a 3+ charge on the aluminum cation and a 1- charge on the chloride anion.
