Students identify the type of bonding between two atoms of elements given their electronegativity values. They study the trend of electronegativity across the periodic table in small groups.

Tidy slides and lecture notes for each are included in this presentation on alloys. Instruction begins with the molecular arrangement of a pure element, gold, and progresses to a few example alloys: brass, steel, and nitinol. This...

Students study energy generation by the Sun, which involves atoms and nuclei.

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

In this science worksheet, students choose the multiple choice science term that best matches the 15 definitions stated. Students circle their answers.

In this molecular formula worksheet students fill in a table describing elements and chemical formulas. They identify, elements by type and how they bond. The student analyze molecular formulas to identify the number of atoms and if the...

In this balancing chemical reactions worksheet, students balance equations, identify electrons gained or lost in atoms and identify the number of atoms of each element for the reactants and products in equations. They also answer 3...

You may want to make a few changes before sharing this slide show with your chemistry class. For one, remove the bright blue swirly background that makes the black font hard to read. Ionic bonds are described with the use of an electron...

Students create a model of a column of air and discover one of the reasons why low and high pressure systems exist and why low pressure is often associated with bad weather.

For this creating bonds worksheet, students create 2-D and 3-D models of the molecular formula provided. Students complete a chart of information about the molecular formula given.

Young scholars articulate a possible relationship between arsenic and gold deposits in a written statement using data to substantiate the relationship they describe. They use real data to determine the source of the arsenic in the...

Students identify the different periodic trends. In this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.

Students explain how elements are arranged in the periodic table. In this chemistry lesson, students group the eggs according to a certain pattern. They compare this to elements in the periodic table.   

Thirty multiple-choice questions and their answers are provided in this resource. It was written for a general chemistry course and queries test takers on scientific notation, mixtures, chemical symbols, electric charges, Dalton's atomic...

Starting with a recap of atomic structure, these slides continue by comparing different isotopes of uranium and explaining which are stable and which have a decay period and emit alpha or beta particles. Gamma decay is just mentioned on...

The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...

The first of two worksheets methodically prepares chemistry novices for naming polyatomic compounds. It begins by having them acknowledge the number of each atom contained in a molecule. Then learners list the valence electrons for a...

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

Learners 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

Using a chart of student test grades as an example, curious chemists learn how to calculate weighted averages. They apply this knowledge to elements on the periodic table. As practice in calculating average atomic masses, learners...

A splendid chart of information about chemical bonding tops the first page. In it you will find information on London forces, permanent dipoles, hydrogen bonds, ionic bonds, and covalent bonds. A four-step process for assigning...

A simple set of slides shows chemistry novices how to name binary compounds containing two nonmetals. Instruction and examples are given, making this a practical presentation for your class. Please note that the links to worksheets on...

Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...

An introduction to the noble gases shows how full electron shells on an atom makes an element unreactive. Your class will then develop an understanding of how sodium and chlorine react ideally because of their electron arrangement....
