The factor that affects how easily an electron can be removed from an atom is the A. structure of the atom. B. size of the atom. C. temperature of the environment. D. surrounding atoms. Weegy: The factor that affects how easily an electron can be removed from an atom is known as ionization energy. Ionization energy, abbreviated IE, is the amount of energy that is required in order to take one electron from an atom. [ The more electrons that are removed, the more ionization energy is required to remove them. The number of IEs it takes to remove an electron is always counted as a positive number, there are never negatives because the removal of electrons always takes energy. ] (More)
