The spacial arrangement of atoms in a molecule has a massive role in the properties of that substance. This pathway provides resources to explain why molecules take the shapes that they do, and how to determine what shape the molecule will take.
The periodic table of elements is one of the greaest achievement in chemistry, and understanding its arrangment helps us to understand many aspects of chemistry. This pathway provides resources to understand several of the trends on the periodic table, such as electronegativity and the number of bonds an atom can form.
An interactive simulation that teaches about polarity, electronegativity, and bonds by changing the electronegativity of atoms and bond angles in a molecule to see how it affects polarity. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional materials.
Explore molecule shapes by building molecules in 3D. How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom. Then, compare the model to real molecules!
Students studying molecule shapes will better understand its concepts with this virtual experiment that tests how a molecule's shape changes due to repulsions between atoms. Learning is further enhanced by building molecules in 3D.
Principles of Macroeconomics 2e covers the scope and sequence of most introductory economics courses. The text includes many current examples, which are handled in a politically equitable way. The outcome is a balanced approach to the theory and application of economics concepts. The second edition has been thoroughly revised to increase clarity, update data and current event impacts, and incorporate the feedback from many reviewers and adopters. Changes made in Principles of Macroeconomics 2e are described in the preface and the transition guide to help instructors transition to the second edition. The first edition of Principles of Macroeconomics by OpenStax is available in web view here.
