The atomic numbers of Ne, Mg. Al and P are 10, 12, 13 and 15. Out of Ne, Mg^(2+),Al^(3+) and P^(3-) , electronic structure of whichelement /ion differs?

Answer»

<P>NE
`MG^(2+)`
`Al^(3+)`
`p^(3-)`

Solution :In Ne `Mg^(2+) and Al^(3+)` there are 10 electrons. So their electronic configuration is same. Whie is `P^(3-)` there are 18 electrons. HENCE its electronic configuration differs.
