Students cut light bulb shapes out of coffee filters or filter paper and use water-soluble markers, pipe cleaners, and water to create a colorful display.
With the ever-changing nature of the Internet, links may be become broken or websites are no longer available. This lesson was developed by Lindsay Bogner during her student teaching experience with me.Use the periodic table as a model to predict the relative properties and trends (e.g., reactivity of metals; types of bonds formed, including ionic, covalent, and polar covalent; numbers of bonds formed; reactions with oxygen) of main group elements based on the patterns of valence electrons in atoms. Analyze data such as physical properties to explain periodic trends of the elements, including metal/nonmetal/metalloid behavior, electrical/heat conductivity, electronegativity and electron affinity, ionization energy, and atomic-covalent/ionic radii, and how they relate to position in the periodic table.5.Plan and conduct investigations to demonstrate different types of simple chemical reactions based on valence electron arrangements of the reactants and determine the quantity of products and reactants.The students will be able to identify and state the correct name and charge for the common monatomic and polyatomic ions.Students will use the monatomic and polyatomic ions to write the correct chemical formula for a compound or name an ionic chemical compound correctly.
element Definition: A substance composed of one type of atom and cannot be chemically separated Context: Antoine Lavoisier was the first to define an element as a pure substance that cannot be broken down.
