Verified step by step guidance

Step 1: Identify the element and its charge. The ion given is Al^{3+}, which means it is an aluminum ion with a +3 charge.

Step 2: Understand the naming conventions for cations. For metal ions like aluminum, the name is usually the element name followed by the charge in Roman numerals in parentheses if the element has multiple common oxidation states.

Step 3: Determine if the charge needs to be specified. Aluminum typically forms only one common ion with a +3 charge, so the charge is often omitted in the name.

Step 4: Review the options: 'Aluminum(III) ion' specifies the charge explicitly, 'Aluminum ion' is the simple name without charge specification, 'Aluminate ion' refers to a polyatomic ion containing aluminum and oxygen, and 'Aluminide ion' refers to an anion of aluminum with a negative charge.

Step 5: Conclude that the correct name for Al^{3+} is 'Aluminum ion' because aluminum commonly forms only the +3 ion, so the charge does not need to be specified.
