Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry #22
 
09:46
Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike with human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about. If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law. -- Table of Contents Bonds Minimize Energy 01:38 Covalent Bonds 03:18 Ionic Bonds 05:37 Coulomb's Law 05:51 -- Want to find Crash Course elsewhere on the internet?

Polar & Non-Polar Molecules: Crash Course Chemistry #23
 
10:46
*** PLEASE WATCH WITH ANNOTATIONS ON! SOME INACCURACIES IN GRAPHICS ARE NOTED AND CORRECTED IN ANNOTATIONS. THANKS! *** Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or non-polar, which describes a kind of symmetry - not just of the molecule, but of the charge. In this edition of Crash Course Chemistry, Hank comes out for Team Polar, and describes why these molecules are so interesting to him. You'll learn that molecules need to have both charge asymmetry and geometric asymmetry to be polar, and that charge asymmetry is caused by a difference in electronegativities. You'll also learn how to notate a dipole moment (or charge separation) of a molecule, the physical mechanism behind like dissolves like, and why water is so dang good at fostering life on Earth. -- Table of Contents Charge Assymetry & Geometric Asymmetry 01:33 Difference in Electronegatives 01:49 Hank is Team Polar 00:33 Dipole Moment 03:49 Charge Separation of a Molecule 04:12 Like Dissolves Like 04:41 Water is Awesome 05:10 -- Want to find Crash Course elsewhere on the internet?

The Octet Rule: Help, Definition, and Exceptions
 
04:45
The Octet Rule is a general rule that is used to describe chemical bonding and draw Lewis Structures. The rule states that Main Group elements form bonds in a manner that results in each atom having eight valence electrons in the highest energy level (sometimes called outer shell). This results in each atom having the same electronic configuration as a noble gas. For a complete tutorial drawing Lewis Structures, watch my video: https://youtu.be/1ZlnzyHahvo The Octet Rule doesn’t work all the time and there are many exceptions. Hydrogen is one of the most notable exceptions and only needs two electrons to fill its outer shell. There are numerous other exceptions including expanded octets which can have up to twelve valence electrons. Even with the exceptions, the Octet Rule is a valuable rule of thumb that helps scientists predict how atoms will bond to form compounds. These predictions are often what is ultimately unobserved in the lab. Drawing/writing done in InkScape. Screen capture done with Camtasia Studio 4.0.

A video tutorial for how to draw Lewis Structures in five steps. The video covers the basic Lewis structures you'll see in an introductory chemistry class. Get more chemistry help at www.Breslyn.org. The five steps are: 1. Find the total valence electrons for the molecule. 2. Put the least electronegative atom in the center. Note: Hydrogen (H) always goes outside. 3. Put two electrons between atoms to form a chemical bond. 4. Complete octets on outside atoms. 5. If central atom does not have an octet, move electrons from outer atoms to form double or triple bonds. Lewis Structures are important to learn because they help us predict: - the shape of a molecule. - how the molecule might react with other molecules. - the physical properties of the molecule (like boiling point, surface tension, etc.). --- Drawing done in Adobe Illustrator and captured with Camtasia Studio on a Microsoft Surface Pro 3.

A step-by-step explanation of how to write the Lewis Dot Structure for CO2 (Carbon Dioxide). Get more chemistry help at www.Breslyn.org. For the CO2 Lewis structure, calculate the total number of valence electrons for the CO2 molecule. After determining how many valence electrons there are in CO2, place them around the central atom to complete the octets. Carbon (C) is the least electronegative atom in the CO2 Lewis structure and therefore should be placed at the center of the structure. The Lewis structure for CO2 has a total of 16 valence electrons. In order to complete the octets for all of the atoms in the structure you will need to form two double bonds. The Lewis dot structure for CO2 frequently shows up on general chemistry tests due to its importance.

The strength of the bond is determined by the charges in the constituent atoms. As the charge increases the bond energy increases and the bond length decreases. Increasing numbers of bonds will also increase the energy and decrease the length. Do you speak another language?

[email protected] Music: "East Side Bar" by Josh Woodward - http://www.joshwoodward.com/ .................................................................................................. Chemical bonds are what hold atoms together. A chemical bond is an attraction between atoms that allows the formation of chemical substances. The electrons that participate in chemical bonds are the valence electrons, which are the electrons found in an atom's outermost shell. An ionic bond is formed when one of the atoms will lose its electron to the other atom. This results in a positively charged ion, called an cation. and negatively charged ion, called an anion. Positive and negative attract! The result is ionic bond. Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms There are also what is called Polar Covalent Bonds. These are Covalent bonds in which the sharing of the electron pair is unequal. The result is a bond where the electron pair is displaced toward the more electronegative atom.

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.

How To Calculate Oxidation Numbers - Basic Introduction
 
31:15
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.

The periodic table of elements is a concise, information-dense catalog of all of the different sorts of atoms in the universe, and it has a wealth of information to tell us if we can learn to read it.

Molecular Shape and Polarity: How to determine whether a molecule will be polar or nonpolar
 
07:29
http://purplebonding.com A polar molecule is a molecule that has poles -- a positive and negative pole to be exact. To determine whether a molecule is polar, you first need to determine if the bonds between the atoms are polar. Next, you use VSEPR, valence shell electron pair repulsion theory, to predict the shape of the molecule. Some shapes will cause the dipoles to cancel out, much as in an even-sided tug-of-war. Some shapes will be asymmetrical, and the dipoles will not cancel out. These factors explain why carbon dioxide CO2 is nonpolar, whereas water H2O is. Watch the video to learn more about determining molecular polarity.

Electron Configuration
 
10:17
005 - Electron Configuration In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law and studying the first ionization energies of different atoms. ANSWERS: Cl - [Ne] 3s^2 3p^5 Ag - [Kr] 4d^10 5s^1 - Did you get [Kr] 5s^2 4d^9? There are a few exceptions to this law. Most of them are found in the f-block metals and they are not of much chemical significance.
