In this ions activity, students answer a variety of questions about anions and cations as well as the octet rule and valence electrons. Types of questions include fill in the blanks, true and false and matching. They solve 3 problems including drawing Lewis structures, writing the number of electrons lost or gained in ions and describing metal and nonmetal ions.
The Three E's - Exciting Energetic Electrons
Students perform flame tests on salts and record the electron configurations for various cations. They analyze and record the results using spectroscopes.
Anions and Cations
In this anions and cations worksheet, students combine eight anions with eleven cations to form molecules. Students name the ions, the chemical name and the formula for each.
Predicting the pH of Salt Solutions
A single page provides you with lecture notes for your lesson on hydrolysis. Introduce your chemistry class to Bronsted-Lowry theory by explaining the hydrolysis of acidic cations and basic anions. Show them how the resulting pH can be determined. Equations for representative chemical reactions are provided to sue as examples. Exeptions are mentioned as well.
Addition Polymerization: Preparation of Polystyrene Using Two Types of Initiators
Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There are not a lot of teacher's notes included, but the lab sheet for learners is explanatory. This is a terrific lab activity for AP classes or those studying organic chemistry.
Chemistry students review the trends found in the organization of the periodic table by completing this worksheet. They determine which of the given atoms has the largest ionic radius and which is the most electronegative. This worksheet has 6 matching, 4 true or false, 10 fill in the blank, and 2 problems to solve. It is neatly formatted and pertinent to any general chemistry curriculum.
Common Ions and Formulae of Ionic Compounds
This is not a activity per se, but rather a reference sheet for your chemistry class. It displays a list of cations and anions along with their chemical symbols and net charges. Following the table is a pretty thorough explanation of how to combine these ions to form ionic compounds. This is a valuable tool to accompany your lesson on ionic compounds. Make sure to assign a few practice problems for homework!
Conductivity - Pass the Buoy and Pepper, Please
Buoys around our coastlines are equipped with sensory devices which monitor temperature, salinity, and water pressure. Emerging earth scientists examine some of this data and relate salinity to the electrical conductivity of the surface of the ocean. A worksheet is provided to guide your oceanographers through this data analysis, and there is also a link to an online salinity calculator.
Cation Separation and Identification
Students conduct an experiment in which they systematically separate cations from a mixture of substances. They use the following types of reactions to do so: precipitation, acids and bases, oxidation and reduction. They compare a standard solution to a waste-water solution to determine which cations are present.
Chalkboard Challenge: The Periodic Table and Periodicity
In a well-prepared Jeopardy-style game, your chemisty class can review the periodic table. Questions cover the element groups, some history, atomic number, atomic and ionic radii, electronegativity, and the shielding effect. What a fun way to prepare for a quiz or exam!
Charge and Electricity
In this electricity worksheet, high schoolers read about electric charge, ionic notation, and conductors and insulators. Then students complete 19 matching, 6 fill in the blank, and 2 short answer questions.
Charge and Electricity
In this charge and electricity worksheet, students read about electric charges and how they are created in atoms. They also read about the unit of charge, called the Coulomb, conductors, and insulators. Emerging electricians match 11 terms to their definitions, they identify charges on atoms, identify conductors and insulators and they label the parts of a charged particle or atom. To top things off, this worksheet is just plain cute!
Common Ions and Formulae of Ionic Compounds
Produced in the UK, this handout contains a chart of cations and anions. It explains how ionic compounds are formed and named. This is a concise and attractive handout that can be useful as a reference for your chemistry apprentices.
The Two Koreas: Will They Ever Reunite?
Students examine the possibility of reunifying Korea. In this Korean history lesson plan, students investigate the events that led to the creation of North and South Korea. Students compose position papers that feature the topic of Korean reunification.
Naming Compounds Handout
In this naming compounds worksheet, students read through guidelines on naming different types of chemical ions and compounds then practice naming on their own. The naming compounds handout includes 100 practice problems in which they name ions, combine pairs of ions to make new formulas, write the ions and chemical formulas for compound names, name molecular compounds, name acids, and finish with naming additional chemical compounds by applying all they have studied in the packet.
The Nature of Salt
Students record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights
Students receive a basis for understanding the three main classifications of rock: igneous, sedimentary and metamorphic. They engage in a hands-on activity designed to give them an appreciation for rocks and minerals.
Identification of Different Compounds and Substances
Learners conduct a series of tests to identify unknown compounds. In this chemistry lesson, students compare the physical and chemical properties of substances. They collect data and formulate a conclusion.
Soil Acidity and Leaching
Young scholars are introduced to the concept of acids and bases and arouse curiosity about acids and bases in daily life. They are introduced to the measurement of soil pH. Pupils are introduced to the effect of soil pH on nutrient cycling and loss. They are also introduced to the environmental impact of soil acidity.
Chemical Names and Formulas
In this chemical formulas worksheet, students answer 5 multiple choice questions and they practice naming compounds and writing formulas for 15 questions.
