Young mathematical scientists interact with protons and electrons in an atom to create a neutrally charged atom. They answer questions based on their findings throughout the interactive resource.

Atomic theory, a periodic table, and a place to practice making atom models without having to draw every proton, neutron, electron, and orbital! This resource is colorful, visually pleasing, and easy to use. 

Up and atom! After labeling the parts of an atom, young chemists answer 16 diagram-based questions that deal with protons, neutrons, electrons, and atomic number.

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements,...

In 1897, J.J. Thomson discovered the electron, the first subatomic particle proven to exist. Scholars review their understanding of electrons, protons, and neutrons as they work through the puzzles. Each puzzle connects two or three...

In this general chemistry assessment, students complete a series of multiple-choice and short-answer questions on elements, chemical properties, and various chemical reactions.

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

In this chemistry worksheet, learners complete a set of multiple-choice and short-answer questions on protons, electrons, ionization, and chemical equations.

Changing the number of neutrons in an atom makes it an isotope, but it does not change the element. Pupils complete logic puzzles, matching isotopes with their unique number of protons, neutrons, and electrons. Either on paper or timed...

Students use reference skills to locate information about the periodic table. They identify elements by name, atomic number, atomic mass, symbol and properties. Students use mathematical processes to find the number of protons,electrons...

Students review atomic structure and then participate in a activity in which they categorize several "elements" into some form of order based on their properties. They discuss the trends they see. They also practice several electron...

Guide first-time physical science learners through the periodic table of elements by having them record the atomic number, atomic mass, number of electrons, number of protons, number of neutrons, or the name of an element when given it's...

Learners spend this lesson plan discovering how electricity makes the appliances in their kitchen operate. In groups, they explain how energy is being converted in a microwave oven and practice giving others directions to how to use...

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 observe the periodic table and draw the Lewis Dot Diagram.  In this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they...

Students review atomic numbers, positive and negative charges, and the periodic table. They examine the relationships among protons and electrons, location of various elements, electron energy levels, and oxidation numbers.

Eighth graders identify the types of bonds elements form. In this chemistry lesson, 8th graders represent valence electrons with dot structures. They draw and label different atoms.

Students examine electric fields using viewers to discover the direction of positive charges and the location of the field's strength. They experiment with positive, negative, like and opposite charges. Students also describe how...

Students practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.

Eighth graders investigate the different elements of the Periodic Table. In this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

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