Students will: determine the number of protons, neutrons, and electrons for a given element by using the periodic table; construct and draw models and diagrams of atoms; use the concept of the stable octet to predict simple molecular formulas; and distinguish between elements and compounds.
In this activity, students determine the number of valence electrons for a …
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: determine the number of valence electrons using energy level diagrams; …
Students will: determine the number of valence electrons using energy level diagrams; explain why elements lose or gain electrons during ionic bonding; define an ion; write correct ion notation; describe some properties of ionic compounds; develop a hypothesis which explains what happens when an ionic compound dissolves.

This resource supports English language development for English Language Learners. Students will study various aspects of atomic theory and elements and incorporate language objectives in this SIOP unit. The resource includes targeted vocabulary, student worksheets, and activities across all language domains.
In this lesson students learn about bond strengths/bond types by observing a …
In this lesson students learn about bond strengths/bond types by observing a demonstration. They apply this knowledge in their own experiments so they can predict bond strengths /bond types based on the locations of the bonding atoms on the periodic table. Students will illustrate the type of bond formed between atoms using 3-D models made from foam balls, toothpicks, rubber bands, and pipe cleaners.

This article can be used with the activity Chemistry in your Bathroom or independently. In this article students will learn about friction, how friction and lubricity work, and esters as a functional group. Other topics briefly discussed in this article are oxidation and crude oil. There are extension activities for students to enhance learning at the end of the article.

This resource is a compilation of text and other elements that serves as a multimedia learning experience for students. The resource reviews atomic structure and how the numbers of subatomic particles determine an element's identity, its placement on the periodic table, and its chemical reactivity.
In this activity, students use a map of electron configuration (patterned after …
In this activity, students use a map of electron configuration (patterned after the Bohr model) and round markers (bingo chips or other similar object) to configure electrons for assigned elements.
In the lesson, students will describe the development of the periodic table …
In the lesson, students will describe the development of the periodic table as a result of the contributions of Mendeleev and Mosely. Students will also explain how the organization of the periodic table and periodic tendencies relate to electron distribution as well as using the periodic table to write electron distributions.
Students will focus on the first 20 elements. Students will first look …
Students will focus on the first 20 elements. Students will first look at a diagram and animation to understand the basic pattern of the arrangement of electrons on energy levels around an atom. Students can be given cards with information about the electrons and energy levels for each of the first 20 atoms. They can try to correctly match the cards with the element. This lesson includes, with direct links to, a student activity sheet, an image of an energy level cross section, an image of an oxygen atom, an image of a periodic table of energy levels, videos on sodium in water, potassium in water and calcium in water as well as sodium, potassium and calcium in acid, an answer key for the student activity sheet and a teacher background section on energy level models.

This interactive periodic table shows the relationships among the elements and illustrates the electron configurations responsible for each element's chemical properties. In the "Mystery Elements" section, students identify and place unknown elements in their correct location on the table, based on their physical and reactive characteristics.
An interactive periodic table that provides not just the basic information, but …
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.
Students will relate chemical properties of elements to their position in the …
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.
This lesson will help students grasp the relationships among protons and electrons, …
This lesson will help students grasp the relationships among protons and electrons, locations of various elements, electron energy levels, and oxidation numbers. Students will draw and analyze electron energy level diagrams and then determine the oxidation number based on their diagrams.
In this activity, students will be provided a blank periodic table and …
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.
