1.	The incorrect statements among the following isA. the firstr ionisation potential of Al is less than the first ionisation potential of MgB. the second ionisation potential of Mg is greater than the second ionisation potential of NaC. the first ionisation potential of Na is less than the first ionisation potential of MgD. the third ionisation potential of Al
Answer» `IE_(2)` of Mg is lower than that of Na because in case of `Mg^(2+)`, 3s electron has to be removed while in case of `Na^(+)`, an electron from the stable inert gas configuration (neon) has to be removed.
