Before the element scandium was discovered in 1879, it was known as “eka-boron.” Predict the properties of scandium from averages of the corresponding properties of its neighboring elements in the periodic table. Compare your predictions with the observed values in Appendix F.
Photoelectron spectroscopy studies of silicon atoms excited by X-rays with wavelength 9.8901010m show four peaks in which the electrons have speeds 2.097107ms1,2.093107ms1,2.014107ms1, and 1.971107ms1 . (Recall that 1J=1kgm2s2 .) (a) Calculate the ionization energy of the electrons in each peak. (b) Assign each peak to an orbital of the silicon atom.
The energy needed to remove one electron from a gaseous potassium atom is only about two-thirds as much as that needed to remove one electron from a gaseous calcium atom, yet nearly three times as much energy as that needed to remove one electron from K+ as from Ca+ . What explanation can you give for this contrast? What do you expect to be the relation between the ionization energy of Ca+ and that of neutral K?

Explain why the 2- ion is the one that tends typically to form. In what group of the periodic table is S located?
If we say that electrons travel around the nucleus of an atom in rings or shells, we can assign that ring a limit on how many electrons they can carry. We say that the ring that surrounds the nucleus has room for 2 electrons, then each ring after that has room for 8 electrons. The outer most ring is called the valence ring or valance shell and may or may not be full. Realistically, this might not be the most accurate way to diagramming electron distribution, but it helps us to see why they are where they are on the table and why they bond the way that they do. It also helps us establish the Group number at the top of each column. Let’s look at Carbon (C) – Given that C has an atomic number of 6: How many protons does it have? D How many electrons does it have? E How many are in the first ring? F Second ring? G Draw the number of electrons around each of these elements on your periodic table. What…
