This concise collection of images speaks volumes about the trends in the periodic table of elements. Different versions of the periodic table are displayed demonstrating different trends. Teachers' notes are included to assist your...

We are family! Why are elements in the same group so similar in many ways? Science scholars explore the relationship between valence electrons and an element's characteristics through a video from the JFR Science playlist. The narrator...

In this periodic table worksheet, students experiment with metals to determine their properties and trends in metal activity. They also find an unknown alkaline earth metal after observing calcium, magnesium and aluminum.

In this periodic table and periodicity worksheet, students define 23 terms related to the groups and periods in the periodic table, the periodic trends, ions, and periodic law.

Thorough explanations of the trends in the periodic table of elements make up the majority of this handout. Atomic and ionic size, ionization energy, electron affinity, and electronegativity are presented before giving chemistry...

Students predict element properties using the periodic table. In this chemistry lesson, students construct a periodic table for elements on the imaginary planet Xeno. Students create vocabulary puzzles and exchange it among themselves.

This compendious collection of slides leaves no questions when it comes to the concept of atomic size. Thorough and easy-to-read graphs, tables, and graphics explain atomic radii, the shielding effect, the octet rule, isoelectric...

In this chemistry olympiad problem solving worksheet, chemistry pupils solve eight problems on a variety of topics including periodic trends, phase changes, ionization reactions, catalysts and titrations.

A variety of topics including reaction rates, combustion reactions, periodic trends, and ionization reactions are included in this exam. Test takers also practice calculating empirical and molecular formulas of compounds.

Is assembling the periodic table as simple as Tetris? Scholars arrange colored cards into a logical order and then make connections to the arrangement of the periodic table. Hands-on activities include adding trend arrows and analyzing...

If your pupils think Um is the element of confusion, this presentation on period trends can only help. It covers the patterns for atomic radii, ionization energy, and electronegativity across a period and down a group. 

In this periodic trends worksheet, students compare the physical and chemical properties of elements by their position in the Periodic Table. Some of the properties investigated are ionization energy, electron affinity, and atomic/ionic...

In this atomic structure and periodic table worksheet, students complete a table with isotopes, their atomic masses, the number of protons, neutrons and electrons and mass number. They also find the average atomic mass of atoms and...

In this chemistry worksheet, students write the electron configuration of different elements. They complete 8 exercises on periodic trends.

See what your class knows about the periodic table and the elements with two separate assessments. Each one focuses on atomic weight and radii, ionization energy, and electonegativity.

Learners 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.

The fifth lesson of seven in the series outlines an in-depth analysis of the periodic table. After direct instruction, pupils take turns practicing in the group before beginning independent study. The assessments include a quiz and an...

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...

In this periodic trends worksheet, students determine the trends of electronegativity in the periodic table. Students compare electronegativity and ionization energy. This worksheet has 6 problems to solve.

Have you ever wondered how scientists know the properties of an element before it is discovered? Here is a quick hands-on activity that demonstrates the procedure for organizing the chemical elements in the periodic table. Scholars sort,...

The hostess visits an antique shop and obtains three different metal-made curios. She then has them melted down in a foundry, measuring the temperature at which each becomes a liquid. Since you could never do such an experiment in the...

In this chemistry worksheet, learners complete 5 short answer questions about trends found in the Periodic Table. Answers are included.

Students investigate the properties of elements and periodicity. In this periodicity lesson plan, students observe a bag of 'elements' which are different fruits and classify them in groups and periods, show the periodic relationships...

Why is the periodic table arranged the way it is? As pupils complete the electron configuration of the first 20 elements, they see the relationship to the rows and columns in the periodic table. The video instructor highlights these...
