Some elements are wrongly placed in the ...

Some elements are wrongly placed in the decreasing order of the property mentioned. Rectifying the fault, place them in correct order of the property . Also furnish reason for the correction done.
`NagtMggtAlgtSi` ( First ionization potential ) .

Text Solution

Verified by Experts

`Si gt Al gt "Mg "gt Na` , silicon has highest first ionization potential due to smallest size , Mg is exception. i.e., has higher ionization potential than aluminum because of `ns^(2)` configuration which is stable.
