Question
The incorrect statement among the following is :
Options
A.The first ionization potential of Al is less than the first ionization potential of Mg
B.The second ionization potential of Mg is greater than the second ionisation potential of Na
C.The first ionization potential of Na is less than the first ionization potential of Mg
D.The first ionization potential of Mg is greater than third ionization potential of Al
Solution
(a) is correct because in Mg rlrctron is released from 3s while in Al it cones from 3p(b) is incorrect as I. E2 (Na) > I. E2 (Mg). It is due to complete configuration of Na+
(c) is correct as ENC for Na is less the Mg.
(d) is correct because Mg2+ has complete configuration 2s2, sp6 so I.E3(Mg) > I.E3 (Al )
(c) is correct as ENC for Na is less the Mg.
(d) is correct because Mg2+ has complete configuration 2s2, sp6 so I.E3(Mg) > I.E3 (Al )
