The first ionzation energy generally increases from left to right across a period. However, there are some exceptions to this trend. For example, boron has a smaller ionization energy than beryllium even though it lies to the right of it in the same period Select the statement that explains this exception to the trend in ionization energy. The 2p electron in boron experience a greater effective nuclear charge than the 2s electrons in beryllium, meaning it is easier to remove...

How does the energy possessed by an emitted photon compare to the difference in energy levels that gave rise to the emission of the photon? When a tube containing hydrogen atoms is energized by pass- ing several thousand volts of electricity into the tube, the hy- drogen emits light that, when passed through a prism, resolves into the "bright line" spectrum shown in Fig. 11.10. Why do hydrogen atoms emit bright lines of specific wavelengths...

Answer d
a. (4 points) Write the Hamiltonian for the neutral Li atom, explicitly including each kinetic and potential energy term. b. (4 points) For a one-electron atom, the 2s and 2p orbitals are degenerate. Why does one electron in Li occupy the 2s orbital instead of 2p? How does that relate to the expectation values for the radii of 2s and 2p you computed earlier on this homework? c. (4 points) Li has an ionization energy of 5.39 eV....

Compare the same business processes (inputs) of two similar companies. Recall a business process from a past or current employer and compare that business process to another past employer or another business. For example, compare the process of purchasing supplies at sample company ABC to the same process at sample company XYZ. While processes stay consistent, results from processes will differ between companies. Did the process differ slightly, significantly or not at all between businesses? What were the disparities in...

1. How do you think financial ratios differ across different industries? Compare two industries of your choice and select a few ratios and explain whether you think the ratios would be higher or lower for each of those industries and explain why. 2. What are some uses and limitations of financial ratios?

What similar pieces of information do you think you would get from a dot blot analysis compared to a western blot analysis? Think about the two methods (the western and dot blot) how they differ, what unique benefits might each technique present? When might one be more useful than the other? You have a stock of EDTA (0.1M) and you need 100ml of 3mM EDTA. Explain how you would make up this solution in the lab. A volume of serum...
