Generally speaking electrons are found in shells which we also call principal energy levels located at increasing distances from the central nucleus the first ionization energy or ie with little sub 1 of an atom of an element describes the amount of energy required to remove the outermost electron from an atom of

Gas

Explanation:

Ionization energy is the energy required to remove the most loosely held electron from a gaseous atom or ion. For the first Ionization energy, it is the energy needed to remove the most loosely bound electron from a gaseous atom

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
