Chemistry - Periodic Table of Elements
Part of the Series: Show Me Science Series - Advanced
Chemistry has an impact on every aspect of our daily lives. The most important chemistry reference is the Periodic Table of the Elements. By providing a logical, mathematical method of organization, the table has become a critical tool for students, teachers and scientists around the globe. This program explores the…
Chemistry Periodic Table of Elements Potassium (K) and Magnesium (Mg)
Part of the Series: Show Me Science Series - Advanced
The Periodic Table is organized with elements specified in rows, or periods, according to increasing atomic number. Metals are on the left of the periodic table, while nonmetals are located on the right. Some in the middle are called metalloids because they have characteristics of both metals and nonmetals. The…
Isotopes and Families of Elements
Discover how isotopes, which are different atoms of the same element, can actually differ in their weight because they contain different numbers of neutrons in their nuclei. Also, learn how different kinds of elements are grouped into both general categories (such as metals and nonmetals) as well as specific chemical…
The Amazing Periodic Table
Episode 6 of The Nature of Matter
Investigate an astonishingly powerful scientific tool: the periodic table of the elements. Delve into the insights that led Russian chemist Dmitri Mendeleev to construct the first modern version of the table in the 1860s, and explore the world of information it contains.
Overview of the Periodic Table
This program covers the very important topic of the periodic table. We give an overview of how the periodic table is organized including the periods, groups, noble gases, metals, nonmetals, transition elements, and more. The entire lesson is taught by working example problems beginning with the easier ones and gradually…
The Periodic Table and Periodicity
Part of the Series: Chemistry Series
Animation succinctly develops the relationship between the electronic structure of an atom and its properties, demonstrating clearly why there are families of elements and gradual changes in the properties of elements arranged by atomic number across the table.
The Structure of Atoms and Molecules
Episode 4 of The Nature of Matter
Understand atomic and molecular structure with the help of a simple analogy: the rooms of a house and the collection of houses in a city. See how the electrons of an atom occupy shells, subshells, and orbitals, which give atoms and molecules their distinctive properties.
Elements, Compounds and Mixtures (2nd Ed.)
Part of the Series: Chemistry Series
By showing the viewers a tiny raindrop and the flecks of material within it, it is simple to illustrate the basic types of materials of our world--pure substances (elements and compounds) and homogeneous and heterogeneous mixtures.
Chemistry, 2nd Edition Course
Many students struggle in high school chemistry. Even if they succeed in earning a good grade, they often still feel confused and unconfident. Why is this? And what can be done to help every student succeed in this vitally important course? Success in chemistry, according to veteran science teacher Professor…
Introduction and Philosophy
In this first lecture, Professor Cardulla explains how any student can find success in chemistry by cultivating a meaningful understanding of the concepts and quantitative thinking operations that underlie this often challenging area of study.
Basic Concepts of Quantitative Reasoning
Introductory chemistry is not mysterious: It requires simple quantitative reasoning that comes naturally to most students. You learn about the types of numbers involved in chemistry and how to solve problems commonly encountered in high school chemistry.
Quantitative Reasoning in Everyday Life
Only a handful of important ideas must be mastered in order to be successful at solving chemistry problems. In this lecture, you review some basic guidelines for approaching any chemistry problem and try out your skills on a few sample problems that demonstrate how you can use everyday reasoning in…
