In this activity, students determine the number of valence electrons for a variety of elements. They will then create Lewis structures (using pieces of cereal or small candies as electrons) to show what happens when two of the elements combine via ionic bonding.
Students will be able to:Analyze given characteristics for a particular element and identify the type of element and probable location on the Periodic Table. Explain why elements behave in different ways based on their location on the Periodic Table. Recognize patterns and general locations of elements on the Periodic Table based on the type of element and its characteristics.
This resource sheet reviews electrons' energy levels and sublevels within the atom and provides critical thinking questions to assess student understanding of these concepts.
In this set of videos students will learn about molecular orbital theory.
In this lesson, students will define the term "period", determine the number of energy levels in an atom of an element, define the word "family", determine the number of valance electrons in an atom of an element, determine if an element is a metal, nonmetal, or metalloid, determine if an element is a solid, liquid, or gas at room temperature, and state an element's family name.
An interactive periodic table that provides not just the basic information, but also information about where the element can be found and how it is used.
In this activity, students learn the meaning of Periodicity, how and why the periodic table is organized, and some of the trends in the periodic table. They do this by playing a game that is sort of a puzzle in which there is one piece missing and they need to figure out what it looks like and where it belongs.

Students will relate chemical properties of elements to their position in the Periodic Table and describe trends of the various properties in the Periodic Table, specifically periodicity. Students will practice predicting phsyical and chemical properties and oxidation numbers of elements by using the Periodic Table.
Students will gather quantitative information to construct a graph to show the period trends in electronegativity, electron affinity, and ionization energy. Once, the trends are recognized they will construct a model of these periodic trends using the Alabama Science in Motion Lab (Periodic Trends: Graphs and Straws).
This worksheet provides students practice in determining electron energy levels.
In this activity, students will be provided a blank periodic table and will fill in the electron-dot model for the first twenty elements. This will help students see the relationship between numbers of valence electrons and properties of elements.
Students will write the electron configuration for various elements, given the atomic number. Given the location of an element on the periodic table, students will be able to give the highest energy level the valence electrons are on, and how many valence electrons it has.
