Answer
Explanation:
Step1: Recall electron - proton relationship in ions
In a neutral atom, the number of electrons equals the number of protons. For an ion, the charge indicates the gain or loss of electrons. A positive charge means electrons are lost.
Step2: Determine the atomic number of aluminium
The atomic number of aluminium (Al) is 13, which means a neutral Al atom has 13 protons and 13 electrons.
Step3: Analyze the charge of the aluminium ion
The aluminium ion is (Al^{3 +}), which has a charge of + 3. This means it has lost 3 electrons.
Step4: Calculate the number of electrons in the aluminium ion
The number of electrons in (Al^{3+}) is (13 - 3=10).
