Name the particle whose electronic arrangement is shown in figure.

A

`F^(-)`

B

`N^(3-)`

C

`Ne`

D

`O^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
d
The element with eight protons is oxygen. Therefore, this must be an oxygen atom. There are ten electrons in the shells `( 2+ 8)` , therefore the ion must have a charge of 8-10= -2. The ion is `O^(2-)`.
