The incorrect statement among the fo llowing is:a)The first ionization...
Explanation:
Ionization potential is the energy required to remove an electron from an atom or ion in the gaseous state. The ionization potential of an element depends on its electronic configuration and atomic size.
a) The first ionization potential of Al is less than the first ionization potential of Mg
- Al has a larger atomic size than Mg due to the presence of an extra shell, which results in weaker attraction between the nucleus and the valence electrons, making it easier to remove the outermost electron. Therefore, the first ionization potential of Al is less than Mg.
b) The second ionization potential of Mg is greater than the second ionization potential of Na
- The second ionization potential is the energy required to remove the second electron from the atom or ion. Mg has a smaller atomic size than Na, and the second electron is removed from a cation (Mg+) that has a greater nuclear charge than Na+. Therefore, the second ionization potential of Mg is greater than Na.
c) The first ionization potential of Na is less than the first ionization potential of Mg
- Na has a larger atomic size than Mg, and the valence electron is farther away from the nucleus, making it easier to remove. Therefore, the first ionization potential of Na is less than Mg.
d) The third ionization potential of Mg is greater than the third ionization potential of Al
- The third ionization potential is the energy required to remove the third electron from the atom or ion. Mg has a smaller atomic size than Al, and the third electron is removed from a cation (Mg2+) that has a greater nuclear charge than Al3+. Therefore, the third ionization potential of Mg is greater than Al.
Therefore, the incorrect statement is option 'B', which says that the second ionization potential of Mg is greater than the second ionization potential of Na.

Mg+ has electronic configuration [Ne] 3s1 ...and Na+ has configuration like nenon a nobal gas...so it is easy to remove one electron from Mg+ ...so B is the correct amswer
