Which of the following statements is the best explanation for the sign and magnitude of AH below? I(g) + e¯→ I'(g) AH = -270 kJ/mol O The addition of an electron to I requires the addition of energy, because energy is always required to increase the number of electrons on an atom. The addition of an electron to I requires the addition of energy. because I typically forms cation I*. O The addition of an electron to I releases energy because I" has noble gas electron configuration. O The addition of an electron to I releases energy, because I has a small atomic radius.
