    Which of these metals has the most negative electron  affinity? cobalt E.   copper D.   chromium C.   cadmium  B.   calcium A.   [Ar]4 s 2 [Kr]5 s 2 4 d 10 [Ar]4 s 1 3 d 5 [Ar]4 s 1 3 d 10 [Ar]4 s 2 3 d 7

    Ionization Energy  measures how  readily an atom or ion releases an  electron. As the ionization energy gets  bigger , the tendency to release an  electron gets  smaller . Electron Affinity  measures how readily a  neutral atom can gain an electron. As the  electron affinity becomes  more negative , the  tendency to gain an electron gets  bigger . Atomic radius  measures how strongly  the outer shell valence electrons of an  atom are attracted to the nucleus. The  bigger the atomic radius, the further the  valence electrons are from the nucleus,  the less attraction they experience.

  Atoms can lose or gain electrons to become ions. For cations, electrons are taken away from the outermost subshell,  making cations smaller than their parent atoms. Na: [Ne]3
