[QUOTE="aglo6509, post: 3781207, member: 328076"] [h2]Homework Statement [/h2] The 3s state Na has an energy of -5.14eV. Determine the effect nuclear charge. [h2]Homework Equations[/h2] I believe you have to use: En=-[(13.6eV)Zeff^2]/n^2 [h2]The Attempt at a Solution[/h2] So since Na is in the 3s state, I think n=3. So: -5.14eV= -[(13.6eV)Zeff^2)]/9 -46.3eV=(-13.6eV)Zeff^2 Zeff=sqrt(3.40)=1.85 However the answer in the back of the book is giving me 1.14e, could someone show me my mistake? [/QUOTE]
