A few different types of electromagnetic radiation are listed in the table below. Complete the table by ordering these types of radiation by increasing frequency, wavelength, and energy per photon. For example, select "I" in the second column for the type of radiation with the lowest frequency, "2" for the type of radiation with the next higher frequency, and so forth.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
