The Periodic Table is an interactive Web site where students can learn about the Periodic Table of the Elements: how it is organized (into groups); the atomic structure of each group; characteristics of isotopes; the scientific notation that is used to define atoms and elements; and how the chemical properties of elements are determined by their atomic composition.
Students will explore the basics of the atom and how scientists came to understand its structure, learn how the number of protons in an atom determines what element it is, and discover how elements, which interact to make up all living things and materials in the world, can be organized and understood using the Periodic Table. Students will also learn about atomic structure, including how negatively charged electrons fill the orbitals of atoms and how the placement of electrons affects the chemical nature of elements; students will also learn the notation systems that are used to describe the orbital configuration.
