What is unique about the electron configurations of transition metals? Which electrons of transition metal elements are most likely to be lost during ion formation? How many ions can iron form? Which transition metal forms only one ion? List several uses for transition metals.
There are four ways to find the charge of an element: Use the periodic table. The usual charge of an element is common to its group. Group 1 (Alkali Metals): 1+. Group 2 (Alkaline Earth Metals): 2+. Groups 3-12 (Transition Metals): Variable positive charges. Lanthanide and Actinide Series: Variable positive charges. Group 13: 3+. Group 14: 4+ or 4-
Transition Metal Ions. Most transition metals differ from the metals of Groups 1, 2, and 13 in that they are capable of forming more than one cation with different ionic charges. As an example, iron commonly forms two different ions.
The charges that can result upon the ionization of transition metals, as well as their corresponding Roman numerals, are shown below in Table \(\PageIndex{1}\). Therefore, using the IUPAC system, Fe +2 is called the "iron (II) ion," and Fe +3 is named as the "iron (III) ion."
The transition metals are elements with partially filled d orbitals, located in the d-block of the periodic table. The reactivity of the transition elements varies widely from very active metals such as scandium and iron to almost inert elements, such as the platinum metals.
