Problem 106IE

(a) Write the electron configuration for Li, and estimate the effective nuclear charge experienced by the valence electron. (b) The energy of an electron in a one-electron atom or ion

and n is the principal quantum number of the electron. Estimate the first ionization energy of Li. (c) Compare the result of your calculation with the value reported in Table 7.4 and explain the difference. (d) What value of the effective nuclear charge gives the proper value for the ionization energy? Does this agree with your explanation in (c)?

Step-by-Step Solution:
Step 1 of 3

BIOL 160 Sphack Energy and Redox Reactions Important point key term learning objective Laws of Thermodynamics - 1 law – energy is conserved. o Can’t be created/destroyed. o But it CAN be transformed and transferred nd - 2 law – total entropy always increases in an isolated system  Entropy (S) – amount of disorder in a group of molecules Energy – the capacity to do work or supply heat - Energy exists in 2 ways o Potential energy (aka chemical energy) – hasn’t done anything yet, but has the ability to do.  Example – water particles at the top of waterfalls have a lot of potential
