The correct electron distribution in magnesium ions is represented by option 'A' which is 2, 8.
Explanation:
- Magnesium, with atomic number 12, has a total of 12 electrons.
- In its neutral state, magnesium has 12 electrons distributed in its electron shells as follows:
- The first shell can hold a maximum of 2 electrons, so it has 2 electrons.
- The second shell can hold a maximum of 8 electrons, so it has 8 electrons.
- The third shell can hold a maximum of 8 electrons, but magnesium only has 2 electrons left to fill in the third shell.
- When magnesium loses 2 electrons, it forms a positive ion called magnesium ion (Mg2+).
- The loss of 2 electrons results in the electron distribution of 2, 8 in the magnesium ion.
- The first shell still has 2 electrons.
- The second shell still has 8 electrons.
- Since 2 electrons are lost, there are no electrons in the third shell.
Therefore, the correct electron distribution in magnesium ions is 2, 8.

Electronic configuration of 12Mg atom is = 2, 8, 2
Electronic configuration of Mg2+ ion is = 2, 8, because 2 positive charges means it loses two electrons.
