Here at Chem4Kids you can find some great information about the 11th element in the periodic table, "sodium." Content focuses on sodium's electrons, where you can find sodium in nature and in the home, and how sodium combines with other elements.
Here you can find some great information about the 16th element in the periodic table, "sulfur." Content focuses on sulfur's electrons, where you can find sulfur in nature and in the home, and how sulfur combines with other elements.
Basic properties of the element Gadolinium Includes Bohr model.
A site containing a good deal of elemental information. Information on each element includes atomic number, atomic mass, melting point, boiling point, density, isotopes and more.
Matching game, including matching common ionic charges and ions and the compounds they form and naming of greek prefixes for covalent molecules.
This activity provides a demonstration and lab exploration of one of the main "building blocks" of the periodic table of elements: chlorine. During the lab, students compare physical and chemical properties of chlorine compounds.
This interactive, scaffolded activity allows students to build an atom within the framework of a newer orbital model. It opens with an explanation of why the Bohr model is incorrect and provides an analogy for understanding orbitals that is simple enough for grades 8-9. As the activity progresses, students build atoms and ions by adding or removing protons, electrons, and neutrons. As changes are made, the model displays the atomic number, net charge, and isotope symbol. Try the "Add an Electron" page to build electrons around a boron nucleus and see how electrons align from lower-to-higher energy.

This interactive activity from ChemThink takes a closer look at a covalent bond--how it is formed and how the sharing of two electrons can keep atoms together.

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Celebrate National Periodic Table Day (February 7) with us! This week on Live Science, we will be talking about the process of discovering, or creating, new elements. So far, Berkeley Lab has helped discover 16 elements on the periodic table! Are we close to finding another
This is a lab activity where the students group the given elements as metals, nonmetals or metalloids.

Students learn about the periodic table and how pervasive the elements are in our daily lives. After reviewing the table organization and facts about the first 20 elements, they play an element identification game. They also learn that engineers incorporate these elements into the design of new products and processes. Acting as computer and animation engineers, students creatively express their new knowledge by creating a superhero character based on of the elements they now know so well. They will then pair with another superhero and create a dynamic duo out of the two elements, which will represent a molecule.

Test your electron-configuration skills in this animated exercise. Practice writing the abbreviated configurations for some of the common elements on the periodic table.
This activity is a guided inquiry laboratory in which students perform reactions involving metals and hydrochloric acid in order to determine their activity series.
