After drawing the valence electron distribution of 13 basic elements, there are spaces to draw 18 more complicated molecules.  For each molecule, there is space for a Dot structure and Lewis structure that best describes the...

In this matter and atoms worksheet, high schoolers will fill in the number of protons, electrons, and neutrons for five different atoms. Then students will fill in the blanks of five statements with words from a word bank. Finally, high...

In this chemistry worksheet, students identify and name the number of neutrons, electrons, and protons for each. Then they illustrate how the electrons are arranged in a cloud. Students also find the relative number of atoms in the two...

In this electron worksheet, students read about how atoms lose and gain electrons and how they become ions. They are given a table with nine elements and they give the electron configuration, the number of electrons, the number of...

As an atomic structure reference and review tool, this handout fits the bill. The first page provides definitions and tables of orbitals, electrons, and energy levels. The second page is an opportunity to practice determining numbers of...

In this interactive Internet  assignment, physical science investigators answer 11 questions about the atom, the subatomic particles, and atomic structure. They can click on "Reveal Answer" to discover if they are correct. They also...

Perfect for reviewing atomic components, this activity simply consists of a large, easy-to-read chart of 11 elements. Chemistry learners fill in the missing element symbol, number of protons, neutrons, and electrons, the atomic mass and...

Using the periodic table of elements, young chemists fill in a chart of isotopes to show the atomic number, mass, charge, number of protons, number of neutrons, and number of electrons. The chart is followed by 11 questions that...

All you will find here is a simplistic chart of 17 elements (hydrogen is repeated) for chemistry beginners to fill in. They list atomic number, mass, and the numbers of protons and electrons. There are three critical thinking questions...

In this chemistry worksheet, students complete the table for each element by writing the electron configuration of the element and giving the values of the four quantum numbers. They also create an energy level diagram for their element...

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.

Lewis acids and bases, Brønsted-Lowry acids and bases, ionization, and more are covered by this chemistry handout. It serves as a review of a specific textbook section, but will also serve as a nice review for any general chemistry...

In this ions learning exercise, students complete a graphic organizer by filling in the number of protons and electrons plus the charge of the given ion.

An engaging activity enlightens young chemists in this lesson on atomic structure. They play musical chairs through a series of concentric circles that represent electon orbitals. A laundry basket in the middle holds the protons and...

In this static electricity learning exercise, students experiment with balloons, plastic bags and flannel clothes to observe attraction and repulsion of objects. Students complete three data tables indicating the charge on the objects...

In this atomic particles worksheet, students complete an elements chart comparing atomic number, mass number, protons, neutrons, and electrons. Students write the electron configuration for atoms. This worksheet has 1 graphic organizer...

For this atom worksheet, students read a paragraph about how atoms become positively and negatively charged. Students complete 6 short answer questions based on the reading.

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,...

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

In this naming and covalent compounds worksheet, students answer 6 questions about ion notation, they make 6 ionic compounds, they make 6 covalent compounds and they name 10 compounds which are ionic, covalent or polyatomic.

For this molecules worksheet, students review the parts of an atom and use element mass to determine isotopes. Students give the group, period, and classification for the given elements. This worksheet has 6 short answer questions and 17...

In this Bohr atom worksheet, students complete a table with the number of electrons of the element, the electron configuration, the mass number, the number of protons, the number of neutrons, the element, the symbol and the isotope...

For this chemical bonds worksheet, students review the different types of bonds, Lewis dot structures, ions, and molecule shapes. This worksheet has 10 matching, 17 multiple choice, and 3 drawing questions.

In this atomic notation activity, students fill in a table with the number of protons, neutrons, electrons, mass number and atomic number for particular elements.
