Which of the Following Transition Elements Show Maximum Oxidation State?
Transition elements are those elements found in the d-block of the periodic table. They can form multiple oxidation states due to the presence of unpaired electrons in the d-orbitals. Some of these elements can show maximum oxidation states depending on their electronic configuration. In this article, we will explore which of the transition elements show the highest oxidation states.
Oxidation States of Transition Elements
The oxidation states of transition elements depend on the number of unpaired electrons present in the d-orbitals. Each unpaired electron can form an oxidation state. The maximum oxidation state of a transition element is usually determined by the highest energy configuration of its d-orbitals. The most commonly seen oxidation states of transition elements are +2, +3, and +4.
Which Transition Elements Show Maximum Oxidation State?
The transition elements that show the highest oxidation states include chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), and nickel (Ni). Chromium is capable of forming an oxidation state of +6. Manganese can form an oxidation state of +7. Iron can form an oxidation state of +8. Cobalt and nickel can form oxidation states of +9 and +10, respectively.
To sum up, transition elements can form multiple oxidation states due to the presence of unpaired electrons in the d-orbitals. The highest oxidation states that can be achieved by transition elements include +6 for chromium, +7 for manganese, +8 for iron, +9 for cobalt, and +10 for nickel.
