Know how to assign oxidation numbers in elements, compounds, and ions. Learn the rules and see examples of how to apply them.
The oxidation state of an element is related to the number of electrons that an atom loses, gains, or appears to use when joining with another atom in compounds. It also determines the ability of an atom to oxidize (to lose electrons) or to reduce (to gain electrons) other atoms or species. Almost all of the transition metals have multiple potential oxidation states.

The lesson discusses the significance of oxidation numbers in understanding redox reactions, elucidating rules for their assignment and demonstrating their application in various fields such as electrochemistry, analytical chemistry, and biochemistry. Student Focus: Understand the concept of oxidation numbers and their role in representing electron distribution in compounds. Learn the rules for assigning oxidation numbers based on factors such as electronegativity and the nature of chemical bonds. Identify changes in oxidation numbers to differentiate between oxidation and reduction processes in chemical reactions. Recognize the practical applications of oxidation numbers in fields such as electrochemistry, analytical chemistry, and biochemistry. EXCELLENT VALUE! Print & Go Worksheets - Reading And Comprehension Activities This reading-based lesson explores the fundamental concepts of oxidation numbers and their significance in redox reactions and electrochemistry. By understanding oxidation numbers as formal charges assigned to atoms in compounds, students gain insight into electron distribution and transfer in chemical reactions. Through examples and practical applications, students learn to assign oxidation numbers, identify oxidation and reduction processes, and appreciate the role of redox reactions in various fields such as analytical chemistry and biochemistry. By mastering these concepts, learners develop critical thinking skills, problem-solving abilities, and a deeper understanding of the underlying principles of chemistry, preparing them for further exploration and application of redox chemistry in real-world contexts. ---------------------------------------------------------------------------------------------- We offer a FREE product in this format which we encourage you to download, to see if it works for you and your students.

Electrophilic activation and subsequent reduction of substrates is in general not possible because highly Lewis acidic metals lack access to multiple redox states. Herein, we demonstrate that transition metal-like redox processes and electronic structure and magnetic properties can be imparted to aluminum(III). Bis(iminopyridine) complexes containing neutral, monoanionic, and dianionic iminopyridine ligands (IP) have been characterized structurally and electronically; yellow (IP)AlCl3 (1), deep green (IP–)2AlCl (2) and (IP–)2Al(CF3SO3) (3), and deep purple [(IP2–)Al]− (5) are presented. The mixed-valent, monoradical complex (IP–)(IP2–)Al is unstable toward C–C coupling, and [(IP2–)Al]2−(μ-IP–IP)2– (4) has been isolated. Variable-temperature magnetic susceptibility and EPR spectroscopy measurements indicate that the biradical character of the ligand-based triplet in 2 is stabilized by strong antiferromagnetic exchange coupling mediated by aluminum(III): J = −230 cm–1 for Ĥ = −2J(ŜL(1)·ŜL(2)). Coordination geometry-dependent (IP–)–(IP–) communication through aluminum(III) is observed electrochemically. The cyclic voltammogram of trigonal bipyramidal 2 displays successive ligand-based oxidation events for the two IP1–/0 processes, at −0.86 and −1.20 V vs SCE. The 0.34 V spacing between redox couples corresponds to a conproportionation constant of Kc = 105.8 for the process (IP–)2AlCl + (IP)2AlCl → 2(IP–)(IP)AlCl consistent with Robin and Day Class II mixed-valent behavior. Tetrahedral 5 displays localized, Class I behavior as indicated by closely spaced redox couples. Furthermore, CV’s of 2 and 5 indicate that changes in the coordination environment of the aluminum center shift the potentials for the IP1–/0 and IP2–/1– redox couples by up to 0.9 V.
