ment of elements in the periodic table and the shell structure of atoms. West is peak for neon? Explain based on the Table 3 summarizes atomic orbital assignments for the ionization energy values obtained from the photoclectron spectra of elements 11-20. Table 3. Element Ionization Energy (MJ/mol is 25 2p 3s 45 Na 104 6.84 3.67 0.50 Mg 126 9.07 5.31 0.74 Al 151 12.1 7.19 1.09 0.58 Si 178 15.1 10.3 1.46 0.79 P 208 18.7 13.5 1.95 1.06 S 239 22.7 16.5 2.05 1.00 CI 273 26.8 20.2 2.44 1.25 Ar 309 31.5 24.1 2.82 1.52 K 347 37.1 29.1 3.93 2.38 0.42 Ca 390 42.7 34.0 4.65 2.90 0.59 15. Based on the ionization energy data in Table 3. which orbitals appear to be closer in absolute energy-als and 2s orhital or a 2s and 3s orbital? Explain based on energy as a function of distance from the nucleus. 16. The potencial energies of electrons in an atom are always negative, meaning they are more stable than isolated or "free" electrons . This leads to an apparently contradictory statement that electrons that are higher in enersy have lower - tion energie. Write a shor 1-3 sentence explanation for ionization energy that eliminates poential confusion about these terms 17. The relative energies for the atomic orbital of Mg are shown below Draw lines to shww the approximate relative energies of the Is 2s 2p 3s, and 3p orbitals of AL. -0.74 3s -53L 20 20-25 Energy (MJ/mole) 1s --126 MJ/molo Mo A
