This video offers a in depth review of how to determine the oxidation state of a metal in a coordination compound and also the rules of determining oxidation numbers. Understanding how to determine oxidation states plays a major role in naming compounds as will be shown in future videos. This video is part of a new vlog series for courses at UIC in which key concepts for a quizzes and exams will be highlighted to provide supplement information for courses that have proven to be challenging for students. The goal is to breakdown down information that may be difficult to grasp during class to allow students to develop a sound conceptual understanding of material that will appear on tests. It is important to note that this vlog series is only meant to be used as a supplement to lecture slides, homework, and discussion worksheets/problem sets. One cannot solely rely in these videos to do well in their class; rather, if one is struggling with a certain concept or in need of seeing the application of the concept, this series will aid in improving their overall knowledge.

13.2.3 Explain the existence of variable oxidation number in ions of transition elements. d-block metals can have variable oxidation states since the d electrons are of similar energy and so can be added/removed easily (small energy change). You need to know Cr (+3, +6), Mn (+4, +7), Fe (+3) and Cu (+1). Not all make sense -- don't worry we will only ask about the ones that do!

In this video, we'll learn look at Transition Metals in Ionic Compounds. Transition metals are the elements in the middle of the periodic table, and compounds with transition metals have roman numerals in them. Transition metal elements are able to make multiple ions with different charges, so we need to use roman numeral notation (sometimes called Stock notation) to show what charge the ions have.

We'll learn how to determine the oxidation numbers or oxidation states for a the elements in a chemical compound. The oxidation numbers tell us how electrons are divided up or shared between atoms in a chemical compound. The oxidation numbers also tell us how electrons move in an oxidation reduction (redox) reaction. There are a set a rules that we use to determine oxidation number. Group 1A elements (alkalai metals) always have an oxidation of +1. Group 2A elements (alkaline earth metals) always have an oxidation number of +2. Elements on their own have an oxidation number of 0, and monatomic ions have an oxidation number that is equal to the ionic charge.

This chemistry video tutorial provides a basic introduction on how to calculate oxidation numbers. It discusses how to find the oxidation states of elements such as Zn, O2, F2, and P4 and how to find the oxidation numbers of polyatomic ions such as SO4 2-, PO4 3-, NO3-, ClO4-, Hg2+2, O2-2 and so forth. Examples include transition metals found in ionic compounds such as Fe3O4, V2O5, and K2CrO4. In addition, this video explains what's behind a fractional oxidation state. For instance, the oxidation number of Fe in Fe3O4 is a fraction +8/3. This tutorial relates oxidation states to electronegativity and positive and negative partial charges. Practice problems include OF2, HCl, NaH, BH3, H2S, SO2, NH3, NO2, CH4, and CO2. This video covers all of the rules relating to oxidation numbers. For instance, Hydrogen usually has a +1 oxidation state when bounded to a nonmetal but it tends to have a -1 oxidation number when attached to a metal.

Many practice problems for how to calculate and determine oxidation numbers, often referred to as oxidation states. To figure out oxidation numbers for elements in a compound, we have to look on the periodic table and consult a list of rules. For neutral compounds, the oxidation numbers add up to zero. For polyatomic ions, the oxidation numbers add up to charge of the ion.

This chemistry video tutorial provides a basic introduction into complex ions, ligands, and coordination compounds. A complex ion typically consist of a transition metal cation bounded to ligands which can be neutral molecules or ions. The number of ligands attached to the transition metal ion is known as the coordination number. This video explains how to determine the oxidation state of the transition metal ion in a complex ion and within a coordination compound. A coordination compound consist of a complex ion and a counterion. The counterion may be a cation or an anion. This video briefly discusses werner's theory of coordination compounds and the concept of primary valence and secondary valence as it relates to the transition metal ions in complex ions.

Using a list of simple rules you’ll learn how to find the oxidation numbers for elements and compounds. For each rule there are examples and practice calculating oxidation numbers. Note: at 3:01 the oxidation number for N in N2O should be +1. More practice calculating oxidation number: https://youtu.be/hTjSNTOUcBQ Visit http://www.breslyn.org for more chemistry help and practice. --- General Rules for Determining Oxidation Numbers --- 1. In a neutral compound all oxidation numbers must add up to zero. 2. In an ion the all oxidation numbers must add up to the charge on the ion. 3. Free elements have an oxidation number of zero (e.g. Na, Fe, H2, O2, S8). 4. Fluorine (F) = -1 5. Group 1 = +1 Group 2 = +2 6.Hydrogen with Non-Metals = +1 Hydrogen with Metals (or Boron) = -1 7. Oxygen = -2 (except with Fluorine or Peroxides) 8.

How to assign oxidation numbers to the atoms in a molecule. 1. Elements have oxidation number = 0 2. Hydrogen's always +1 (except in "hydrides") 3. Oxygen's always -2 (except in "peroxides") 4. Other atoms get the charge they prefer, as long as the sum of oxidation numbers for all atoms = the total charge on the atom.

We'll learn how to name ionic compounds that have transition metals in them. The names for transition metal compounds often have roman numerals in them, because the roman numerals indicate the charge on the transition metal. This is because transitional metal elements are able to make a variety of ions with different charge. In order to write the roman numeral for a transition metal compound, we need to work backwards, using the periodic table or a list of polyatomic ions to figure out what charge it has in that particular ionic compound.

We use roman numerals to indicate the charge of a transition metal ion. To write a formula for an ionic compound with transition metals, we make sure that the positive charge of the cation and the negative charge of the anion balance out.
