The decreasing order of the first ionization energy of the given elements is Xe, As, Be, Al. This can be explained by the following points:
1. Nuclear Charge: The first ionization energy of an element depends on the nuclear charge of the atom. The higher the nuclear charge, the more difficult it is to remove an electron from the atom. Xe has the highest nuclear charge among the given elements, followed by As, Be, and Al.
2. Electron Shielding: The first ionization energy also depends on the number of electrons in the outermost shell of the atom and the number of inner shells. The outer electrons are shielded from the nucleus by the inner electrons. The more the number of inner shells, the more the shielding effect. Xe has a larger number of inner shells, resulting in a stronger shielding effect, making it easier to remove an electron from the outermost shell.
3. Atomic Radius: The first ionization energy is inversely proportional to the atomic radius of the element. The larger the atomic radius, the easier it is to remove an electron from the outermost shell. As and Al have smaller atomic radii than Xe and Be, making it harder to remove an electron from their outermost shells.
Based on the above factors, the decreasing order of the first ionization energy of the given elements is Xe, As, Be, Al. Therefore, option C (Xe, As, Be, Al) is the correct answer.
