The Periodic Table: Our Menu of Matter

Human beings have interacted with elements since prehistoric times. Yet large-scale efforts to organize these elements did not come about until the 19th century. In this lesson, become acquainted with the periodic table. Learn about its basic organizing principles and allow Ron to take you on a quick tour of its evolution through time.

From Triads to Tables and the Role of Protons

The periodic table was a collaborative effort that spanned centuries. In this lesson, dig deeper into its early history. Learn about debates surrounding the classification and categorization of elements, and explore how the discovery of subatomic particles, specifically protons, propelled a specific version of the periodic table to the forefront.

How Electrons Shape the Table

What gives the modern periodic table its distinctive shape? The answer: electrons. Understand the relationship between an atom’s nucleus and its electrons, then discover how these peculiar subatomic particles—that do not always behave like particles—determine the number and type of bonds an element can make.

Periodic Trends in Element Properties

What constitutes a “group” of elements? Are neighboring groups similar in some way? And beyond proton counts and electron valences, what other chemical and physical characteristics govern the structure of the periodic table? Better understand how the periodic table brings together elements with similar properties from the size of their atomic radius to their electro-negativity.

The Origin and Distribution of the Elements

Here, grasp how just three elements—hydrogen, helium, and lithium—combined to create new, heavier elements like uranium or sulfur through the complicated process of nuclear fusion. Also discover how natural and cosmic events like supernovas can lead to the creation of new elements through time.

Elements Break Down: Radiation and Fission

A cosmic event is not the only way an element can transform. The processes of transmutation, radiation, and nuclear fission are equally capable of radically altering elements and their behaviors. Familiarize yourself with the ever-important process of transmutation and learn how elements with unstable nuclei break down to produce more stable products through radiation and nuclear fission.
