Interpretation:
It is to be explained why there is a large jump between the second and third ionization energies of magnesium and also the large gap between the third and fourth ionization energies of aluminum.
Concept Introduction :
The first ionization energy is the energy needed for the removal of the outermost electron from the neutral gaseous atom.
While second ionization energy is the energy needed for the removal of the outermost electron from the unipositive gaseous ion.
Answer to Problem 60A
After removing two electrons, magnesium attains a noble gas configuration.
Similarly, after removing three electrons, aluminum attains a noble gas configuration.
Explanation of Solution
The
After removing one electron, the electronic configuration becomes as shown,
Second ionization energy is the energy needed to remove the outermost electron from a unipositive isolated cation. After removing the second electron, the electronic configuration becomes as,
After removing the second electron, the
The atomic mass of aluminum is 13 and its electronic configuration is as shown:
After removing one electron, the electronic configuration becomes as:
Second ionization energy is the energy needed to remove the outermost electron from a unipositive isolated cation. After removing the second electron, the electronic configuration becomes,
Third ionization energy is the energy needed to remove the outermost electron from a dipositive isolated cation. After removing the second electron, the electronic configuration becomes,
After removing the third electron, the
Electronic configurations of elements decide their ionization energy.
