The group 3 (or 3B) transition metals include scandium, yttrium, lanthanum, and actinium. Except for actinium, the group 3 elements are relatively abundant, with a natural abundance on the order of that of metals such as cobalt and nickel. You may also hear lutetium or lawrencium counted as group 3 metals. The electron configuration for both are similar with one electron in the corresponding dorbital. For this tutorial, we will consider the four elements scandium, yttrium, lanthanum, and actinium when answering parts. The group 4 (or 4B) transition metals include titanium, zirconium, hafnium, and rutherfordium. These elements vary widely in abundance, from the relatively abundant titanium and zirconium to rutherfordium, which does not occur naturally. The naturally occurring group 5 (or 5B) transition metals include vanadium, niobium, and tantalum. All three of these elements are normally found in nature as oxide ores in their highest oxidation state, +5. The naturally occurring group…
