Question

Most stable monatomic ion formed from aluminum

Answer 1

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

Answer 2

Answer: The stable mono atomic ion of aluminium is
`Al^(3+)`

Step-by-step 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
`1s^22s^22p^63s^23p^1`

This element will loose 3 electrons to form
`Al^(3+)` ion.

Hence, the stable mono atomic ion of aluminium is
`Al^(3+)`
