the most stable monatomic ion formed from aluminum is Al^{3+}

Answer: The stable mono atomic ion of aluminium is [tex]Al^{3+}[/tex]

Explanation:

Mono atomic ion is defined as the ion which is formed by 1 element only.

An ion is formed when an atom looses or gains electron.

  • When an atom looses electrons, it will form a positive ion known as cation.
  • When an atom gains electrons, it will form a negative ion known as anion.

Aluminium is the 13th element in the periodic table. The electronic configuration of this element is [tex]1s^22s^22p^63s^23p^1[/tex]

This element will loose 3 electrons to form [tex]Al^{3+}[/tex] ion.

Hence, the stable mono atomic ion of aluminium is [tex]Al^{3+}[/tex]
