Answer: The aluminum atom loses electrons to form an ion.

The ion that is formed is positive

Second Part of the question: What is the name of the aluminum ion?

Answer : Al+3

Explanation: An aluminum ion has a charge of +3. It is not a neutral atom. It has a + charge, the electrons must have been taken away (electrons have a negative charge). Since the atomic number is 13, the number of protons is thirteen. In a neutral atom, there would be thirteen electrons. You take away 3. There is 10 electrons in Aluminum Ion.
