Verified step by step guidance

Step 1: Identify the species given, which is the Al^{3+} ion. This indicates an aluminum atom that has lost three electrons, resulting in a positive charge of +3.

Step 2: Understand the naming conventions for ions: a metal cation typically takes the name of the element followed by the word 'ion'. For example, Na^{+} is called the sodium ion.

Step 3: Recognize that 'Aluminum ion' refers to the Al^{3+} cation, which is the aluminum atom with a +3 charge.

Step 4: Differentiate from other terms: 'Aluminate ion' refers to a polyatomic ion containing aluminum and oxygen (such as AlO_2^{-}), 'Aluminide ion' refers to an anion containing aluminum with a negative charge, and 'Alumium ion' is not a correct chemical term.

Step 5: Conclude that the correct name for Al^{3+} is 'Aluminum ion' because it is a simple cation formed by the aluminum atom losing three electrons.
