Periodic table part III: [Lithium] Li & [Beryllium] Be,As we continue our history of the Periodic Table organizational system and discovery of the elements, this program examines the elements lithium and beryllium. The characteristics of alkali metals and alkali earth metals are discussed in detail, with the help of graphics and animation demonstrating their similarities and differences. Students will learn why elements are organized into specific groups and their relations to the rows and columns of the periodic table.

Periodic table part IV: Iron, Zinc, Selenium,The periodic table organizes elements by an atomic number, based on the amount of protons in each element's nucleus. Other factors include electron configuration and recurring chemical properties. Elements are listed in order of increasing atomic number along with its chemical symbol in each box. The elements iron, zinc and selenium help promote health and fight disease and have commercial uses. Iron zinc and selenium, which happen to exist naturally, are also referred to as trace minerals because humans need only small amounts of them.

Periodic table Potassium (K), Magnesium (Mg),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 periodic table is purposely arranged into vertical classifications called groups. Columns of elements help define element groups. Some of the notable groups of elements include the noble gases (column 18), the halogens (column 17), the alkali metals (column 1) and the alkaline earth metals (column 2). The transition metals are located in the center of the periodic table. They include many of the common metals, such as copper, iron, silver and gold. The two rows below the main body of the table are called the lanthanide and actinide series. They include the very heavy metallic elements, such as uranium and plutonium. This program goes in depth regarding the elements potassium (K) and magnesium (Mg) and their roles in the health of the human body. Potassium helps to control the proper balance of fluids in cells, helps with the contraction of muscles, and is involved in the transmission of chemical messages between nerve cells. Potassium aids in digestion of food, and in the proper function of the eyes. Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong.

Periodic table of elements,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 discoveries that led up to the organization of the periodic table and how it is presently organized. It introduces and explores several elements (Hydrogen and Titanium) and their effect on our daily lives and the environments in which they occur.

Chemical engineering: Composites,Composite materials (also called composition materials or shortened to composites) are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. This is an extremely broad definition that holds true for all composites, however, more recently the term "composite" describes reinforced plastics. This program will explain how composites work and what the future holds for these amazing materials.

Battery technology innovations,The battery has been in use since the early 1800s but the last twenty years has seen the most incredible growth in portable energy storage technology. Today, batteries provide power and on-demand energy to much of our modern high-tech world from the small back-up battery in your computer to units large enough to power cars, trucks and space stations. This program will emphasize lithium-ion technology, as well as innovations in the storage and transfer of energy.

Metallurgy,Metallurgy is the study of the extraction, refining, alloying and fabrication of metals and of their structure and properties. Metallurgy can be described as a sub-set of "materials science"--the study of physical and chemical behavior of metals and alloys. This program discusses metal's role in our control of the environment. Advances in agriculture, warfare, transport, even cookery are impossible without metal, as was the entire Industrial Revolution--from steam to electricity.
