A huge collection of slides introduces chemistry learners to the periodic table of elements, electron configuration, and electronegativity. It opens with the history of today's periodic table, and then details the arrangement. After...

Time to put the knowledge to the test! Young scholars take what they know about the periodic table and build their own from scratch. Using clues from 26 different elements, they place elements in a blank periodic table. The clues include...

Ninth graders examine the Periodic Table. In this element lesson, 9th graders observe the chemical reactivity of elements. They graph the properties and discuss the trend in the group and period of elements. The students use math to...

Students review how physical and chemical change while discussing the properties. They diagram the electron dot for the first four elements in the periodic table. Students identify elements and state what they know while investigating...

In this elements worksheet, students write the electron configurations for given elements. Students describe ionization energy and electron affinity and the periodic trends for both. This worksheet has 20 short answer questions.

While this resource does not provide problems for chemistry learners to solve, it outlines skills that they should have and concepts that they should grasp. Topics include thermodynamics, periodicity, redox equilibria, transition metals,...

In this periodic trends worksheet, students solve ten problems related to elements in the periodic table. Students write electron configurations for atoms and they compare elements and their periodic trends.

In this periodic functions worksheet, students use given data of the speed of a star and find the best fit periodic function that follows the trend in data. They determine the amplitude, offset phase and the formula for the angle. They...

Eleventh graders study the use of the periodic table to develop a better understanding of the chemical elements.

For this atomic trend worksheet, students answer questions about trends in the periodic table such as ionization energy, atomic radii and electronegativity. They are given tables of elements and ions and they must identify which ones...

Students gain a perspective in the development of chemistry. They understand some of the topics in their text and the ongoing nature of research. They then will be able to see the trends of the periodic table first hand through their own...

Students, using a Web site about the periodic table of elements, create spreadsheets representing elements and their properties. They also create graphs that compare the physical properties of the elements.

Students research events, trends, and phenomena of specific years in the twentieth century, then design "time capsules" to commemorate those years.

In this chemistry review worksheet, students review terms and concepts covered. Students practice metric conversions, factor labeling, temperature conversions, heat calculations, atomic structure, and gas laws. This worksheet has 3...

Students gather data for the project for the entire year. They plot their data, try to fit a equation to their data, and speculate on why the data shows the pattern it does and project its future growth.

Students observe and perform experiments with sodium, potassium, calcium, magnesium, sulfur ,and phosphorus. The discover trends down groups, across periods, and having to do with the pH of metal oxides vs. nonmetal oxides.

Explore the concept of electronegativity and how it trends across the periodic table of elements. The author uses simple, humorous drawings to help with understanding.
