Final answer:

The correct order for first ionization energies from the choices given is: Al < Si < S < Cl < Ar.

Step-by-step explanation:

The correct order for first ionization energies from the choices given is:

  1. Al < Si < S < Cl < Ar

First ionization energy is the energy required to remove one electron from an atom in the gaseous state. The trend for first ionization energies is generally increasing across a period and decreasing down a group in the periodic table. However, there are exceptions due to factors such as electron configuration and stability.
