Sal reviews the Sn1 and Sn2 reactions with comparable reactants. He discusses which electrons are lost or gained and the conditions that make one or the other process favorable.

This 60-question comprehensive exam was designed to determine who would go on to compete in the 2000 US National Chemistry Olympiad. Hopefuls answer multiple choice questions regarding all chemistry topics taught in the first year...

What a cute approach to chemical bonding! Atoms all have human names and are attending at a dance. Who will pair up with whom? By reading the characteristics, and not the element name, chemistry whizzes figure out the bonding pairs....

This video continues from the previous topic and specifies how the elimination reaction between moderately electronegative molecules is controlled.

A video on Sn1 reactions diagram water and 2-Bromo-2-Methylpropane. Sal discusses the possible behaviors of the valence electrons. He reviews the concepts of nucleophilicity and electronegativity and the speed of each reaction stage.

Sal starts this lecture by presenting the question as it might appear in a test or chemistry problem set. After reviewing the naming of a molecule, and then drawing it to clarify the electron arrangement, he explains how to determine the...

A splendid chart of information about chemical bonding tops the first page. In it you will find information on London forces, permanent dipoles, hydrogen bonds, ionic bonds, and covalent bonds. A four-step process for assigning...

At the top of the page are a reading passage and colorful diagram that depicts the tug-of-war that occurs between bonding molecules due to electronegativity. High school chemists fill in a chart with electronegativity values, the...

A very neat worksheet has been produced by Pearson Education, Inc. for use in a general chemistry class. The first nine questions are fill in the blanks for a paragraph about types of bonds and electronegativity. Five true-false...

Most of the 10 short answer questions on this chemistry handout have to do with electronegativity. There are also few that deal with types of bonds that form. Use this as a homework assignment or quiz.

The properties of water, such as electronegativity, are related to its physical behavior. Water's boiling point, miscibility, and solubility are compared to other substances and related to van der Waal forces.

This concise collection of images speaks volumes about the trends in the periodic table of elements. Different versions of the periodic table are displayed demonstrating different trends. Teachers' notes are included to assist your...

Your young chemists will find these slides very informative. Groups and periods of the periodic table are labeled and described according to the charge. Comprehensive explanations of physical and chemical properties and how they relate...

Starting with an example of how bromide might react with a number of different alkenes, this lecture shows how the valence electrons and electronegativity control the likelihood of reactions.

Here is a thorough review of chemical bonding! Seventeen problems query chemistry learners about electron configuration and ionic bonding, sharing electrons and covalent bonding. Chemistry masters draw Lewis dot diagrams and answer...

Chemists compare the electronegativity, ionization energy, electron affinity, and ionic radius of different elements. This learning exercise is composed of 11 multiple choice questions, and 8 written explanations. Critical thinking...

A huge collection of slides introduces chemistry learners to the periodic table of elements, electron configuration, and electronegativity. It opens with the history of today's periodic table, and then details the arrangement. After...

Thorough explanations of the trends in the periodic table of elements make up the majority of this handout. Atomic and ionic size, ionization energy, electron affinity, and electronegativity are presented before giving chemistry...

Opening with a chart of common polyatomic ions, and finishing with an explanation of how  to name polyatomic ions, this presentation is to the point. The links on the vocabulary page do not work, leaving you only a few slides to work...

In this chemical bonding worksheet, learners answer 76 questions about compounds, Lewis dot structures, intermolecular forces between atoms, electronegativity and bonding and types of bonds.

In this electronegativity worksheet, learners use given electronegativity values for each element to determine the bond type in 9 molecules.

In this trends in the periodic table worksheet, students plot the ionization energy vs. atomic number and they plot atomic radius vs. atomic number of the first 20 elements. Students analyze their graphs and answer questions about the...

In this electronegativity worksheet, learners complete a chart given 10 molecules. They draw their Lewis structures, they draw the shape of the molecule, they determine the difference in electronegativity between the bonds, they...

In this periodic table worksheet, students answer 10 questions about electronegativity, the groups of elements, atomic radius trends, electronegativity trends, ionization energy trends and properties of the elements.
