In this periodic table worksheet, learners will label the atomic number, atomic mass, element name, and element symbol for oxygen. Then students will determine the characteristics of the different groups of elements on the periodic table...

Multiple representations of the varying theories of atomic structure. With these pictures and some background of the theories and scientific figures surrounding them, your class will develop a better understanding of scientific history...

An educational presentation includes atoms, molecules, the four major elements, as well as neutrons and protons. Additionally, slides focus on atomic number, mass number, atomic weight, polar and nonpolar covalent bonding, ionic...

In this chemistry review worksheet, students classify and name compounds, calculate atomic mass, draw Lewis Dot Diagrams, and determine number of protons for atoms. This worksheet has 37 fill in the blank, 38 matching, and 3 short answer...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

In this atom worksheet, students read about Dalton's contributions to the structure of the atom. They answer five questions about Dalton's ideas, the law of multiple proportions and the law of definite proportions.

Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

In this chemistry learning exercise, students read about atoms, their charges, and their parts; protons and neutrons. They examine how to determine atomic weight by looking at an example. They work online as they practice finding the...

In this atom worksheet, students review the subatomic particles, the scientists associated with the atomic theory, and the periodic table. This worksheet has 15 matching, 24 fill in the blank, and 11 short answer questions.

In this history of the atom instructional activity, students answer questions about Thomson's cathode ray apparatus, Rutherford's gold foil experiment and Dalton's beliefs about the atom. Students identify the number of protons, neutrons...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...

Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

For this early atomic theory worksheet, students answer 4 questions about the Law of Definite Proportions, the Law of Conservation of Mass and Dalton's Laws. Students are given 5 statements to determine if each true statement supports or...

Students investigate relative mass using 8 different items. In this relative masses lesson plan, students discuss as a class John Dalton's atomic theory. They take the masses of the 8 items and record their data. They discuss relative...

In this chemistry review worksheet, students read about atoms and the periodic table and they complete a chart using the periodic table to find the atomic number, atomic mass and group of given elements. Students answer 5 questions about...

In this atom worksheet, high schoolers answer 31 multiple choice questions about the structure of atoms, the periodic table, the reactivity of elements, orbital diagrams and the families of elements.

In this atom worksheet, students complete 60 questions about the trends in atoms such as ionization energy and atomic radius, about valence electrons, about the families of elements, about metals, non-metals and semi-metals, about the...

In this atoms worksheet, students complete 58 questions about the atomic radius of atoms, the ionization energy, the valence electrons, metals, non-metals and semi-metals and the families of elements.

In this atomic structure worksheet, students draw a helium atom and show the subatomic particles. They also answer questions about the Bohr model, Dalton's atomic theory and the energy of electrons based on their location in an atom.

In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.
