Give the electronic distribution in magnesium atom and magnesium ion how do these electronic configruation differ?

Explanation

`{:(, K , L , M) , ("Magnesium atom" (Mg): , 2 , 8 , 2),("Magnesium ion" (Mg^(2+)): , 2 , 8 ,-):}`
`Mg^(2+)` ion has only two shells and its electronic configuration is similar to that of noble gas element neon (Ne) Mg atom has three shells with 2 electrons in the outer shell i.e M-shell.
