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 will wear "tags" to identify themselves as common ions and find a classmate that they can "bond" with. Students will record information in a table, including the formula and the name of the compound that is created during the bonding.
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.

This resource is an in-depth discussion, with diagrams, covering the different types of chemical bonding. It details ionic bonds, covalent bonds, polar covalence, and electronegativity.
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 …
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 resource is a compilation of text and other elements that serves …
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 lesson, students will define chemical bond, ionic bonding and properties …
In this lesson, students will define chemical bond, ionic bonding and properties of ionic compounds, and covalent bonding and properties of covalent compounds. Students will also explain polarity in bonds, predict bond types, and define metallic bonding.

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.

This lesson sequence is designed to exemplify an argumentation approach to practical work, using a classification framework. In these lessons students see for themselves that it is possible to group chemicals with similar properties – and that there are some chemicals which do not fit easily into a group. Students carry out a practical activity in one lesson and in the next try to group the chemicals according to the results of their investigations. At the end the students are told the four main groups that chemists use to classify chemicals and they try placing the chemicals they have been using into these groups.

Students will be able to define solubility; identify a substance's bonding (ionic or covalent) from its chemical formula; predict a substance's solubility in water and oil from its chemical formula; determine the effects of temperature and surface area on the solubility copper(II) sulfate; determine the surface area of two different objects; and use the scientific method to gather, organize, and analyze data.
