    Answer:

    \huge\boxed{Answer\hookleftarrow}

    • Ionization enthalpy (IE) is the energy required to remove the highest-energy electron from a neutral atom. In general, ionization energy increases across a period and decreases down a group.
    • So, for your question IE decreases down the group.

    Answer:

    As we move from left to right across a period, the ionization energy of elements increases. This is due to the decrease in the size of atoms across a period.
