Transition Metals in Ionic Formulas
 
08:12
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.

To see all my Chemistry videos, check out http://socratic.org/chemistry Where do electrons live in atoms? They live in energy levels or shells, which are varying distances from the nucleus, and can hold varying numbers of electrons. The most important electrons in an atom are the valence electrons, which are in the outermost energy level or shell. We'll look at how to determine the number of valence electrons in an atom, based on which column it is in on the periodic table.

How to Find Valence Electrons! (and Total Electrons)
 
09:28
You can find valence electrons with a shortcut using the periodic table, but it’s good to only do that after you understand why the shortcut works, and to do that you have to draw out the full electrons and orbitals for a few different atoms. Valence electrons are just electrons in the last orbital, they are different from core electrons, which are the total number of electrons except the valence.

Naming Ionic Compounds with Transition Metals Introduction

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.

This chemistry video tutorial focuses on paramagnetism and diamagnetism. It shows you how to identify if an element is paramagnetic or diamagnetic by writing the ground state electron configuration using noble gas notation and determining if the element has unpaired electrons by drawing the orbital diagram. Elements with unpaired electrons are paramagnetic which are weakly attracted to an external magnetic field. Elements with paired electrons only are diamagnetic and are weakly repelled by an external magnetic field.

How to Calculate Oxidation Numbers Introduction
 
13:26
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.

To see all my Chemistry videos, check out http://socratic.org/chemistry Confused about ions? We'll learn the difference between an atom and an ion. Ions are formed because of a net charge on an atom, because the number of protons and electrons do not balance. This means that the atom is no longer electrically neutral, but is a cation or an anion. We also talk about polyatomic ions.
