An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

In this atomic theory worksheet, students complete a paragraph describing the development of the atomic theory by filling in the blank with 21 terms.

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

Thirty multiple-choice questions and their answers are provided in this resource. It was written for a general chemistry course and queries test takers on scientific notation, mixtures, chemical symbols, electric charges, Dalton's atomic...

In this atomic structure worksheet, learners 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 atomic theory worksheet, students review the observations that led to the conclusion of the atom having a positively charged nucleus. Students compare atomic number and mass number and explain how the discovery of subatomic...

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 atom worksheet, learners define the atomic theory, compare an atom and a molecule, determine atomic number and number of protons for elements, and draw Bohr models for given elements. This worksheet has 4 graphic organizer, 8...

In this early atomic theory instructional activity, 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...

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...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

In this atomic structure learning exercise, students use textbooks and dictionaries to find the definitions of 22 terms associated with atomic structure.

In this atomic theory worksheet, learners use Planck's constant, Rydberg constant, and Avogadro's number to complete 20 multiple choice questions.

Mostly what you will find here is a history of quantum mechanics. Influential scientists are introduced (along with some of their recorded quotes), the progression of atomic models is reviewed, and finally experssions and equations are...

This wonderful recap of powerful figures in scientific history includes pictures, important dates, and the information about their inventions or impact. Atomic structure and the photoelectric effect are introduced. The first slide gives...

Words, words, words! This presentation uses plenty of them to define the atom, outline the history of what we know about atoms, and explain atomic and mass numbers. That's all! Informative, but not interesting, this slide show would be...

Atomic theory as a philosophical study was explored even by the Ancient Greeks. The knowledge of atoms was developed in the 17th century.  This PowerPoint explains how by the 1940's, splitting of the atom was discovered and since...

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

In this bonding activity, students fill in 8 blanks with the appropriate terms about theories of bonding, they determine if 6 statements are true or false, they match 5 terms with their meanings and they solve 1 problem related to hybrid...

In this physics worksheet, students develop an understanding of the atomic model and how atoms relate to one another through answering the seven questions.

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...

Though there are technically only 13 questions on this exam, they take up six pages and make a thorough assessment of organic chemistry principles. There are plenty of diagrams to label or complete. Emission spectra are displayed for...

In this history of the atom worksheet, high schoolers 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 and...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on the entire year's curriculum when they take this 13-page test.
