We're about to move into the modern age of physics. In the early 1800's, scientists began examining the basis of matter, space, and time. Sometimes it gets very confusing, but the big idea is that Newton's physics describe about 90% of...

Describe the difference between the subatomic particles, including their masses, locations, and charges. This lesson is 5 of 7 in the series titled "Subatomic Particles."

This review from the Glenbrook South High School provides a series of questions on various topics associated with static electricity (such as electrical insulation). Answers and explanations are hidden, yet easily accessed from within a...

Site provides the ABC's of nuclear science including radioactivity and gamma decay to fission and comic rays.

This lesson explains what is represented by the atomic mass, and how it varies from one element to the next. Module includes a slideshow and a quiz.

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses electron affinity and ionization energy in relation to ion formation. Charts and graphs are included as well.

The young scholars will review the concepts of electromagnetic spectrum, properties of light, and the transition from ground to excited state of electrons in atoms. In laboratory groups, the students will identify the characteristic...

This diagram shows a basic atom structure with an atom core, proton, neutron and electron.

From the Brockport High School Physics Labs web pages. Includes an excellent graphic depicting the energy levels of a hydrogen atoms and portraying the electron level transitions for the Lyman, Balmer, and Paschen series. Includes both...

In this exercise students will select the electron-pair geometry for a molecule and drag it onto the central atom. Then they will place the terminal atoms in the appropriate positions on the molecule. Finally students will enter the...

In the following activity, students are required to select a central atom, drag an electron-pair geometry and other appropriate atoms in order to create the molecular structure.

[Free Registration/Login may be required to access all resource tools.] Rutherford's model of the atom was better than earlier models. But it wasn't the last word. Danish physicist Niels Bohr created a more accurate and useful model....

Investigate the science involved in the creation of diamonds by building a carbon atom out of quarks and electrons. Observe how carbon atoms are arranged by manipulating a diamond crystal.

This lesson focuses on the periodic table and the configurations. In the modern periodic table, elements are in order of atomic number in periods and groups. Electronic configurations model how electrons are arranged in atoms. A link to...

Discusses research being done with silicene, which is silicon that is one atom thick. Silicene is compared to graphene, both of which have the potential for sparking future innovations in electronics.

Joseph John Thomson, better known as J. J. Thomson, was a British physicist who first theorized and offered experimental evidence that the atom was a divisible entity rather than the basic unit of matter, as was widely believed at the...

This lesson introduces the concept of electricity by asking students to imagine what their life would be like without electricity. Two main forms of electricity, static and current, are introduced. Students learn that electrons can move...

Take an interactive, multiple choice quiz over static electricity. After completing the quiz, check your score, and then revisit any incorrect question for further review.

Activity 4 investigates How does electron distribution impact our observations? Students have described how properties of molecules change depending on what atoms make up the molecule. In this activity students will use those ideas to...

This section of the lesson module focuses on covalent bonds, which are formed between non-metal atoms that share a pair of electrons. It includes links to a video and a test. Other types of chemical bonds are covered elsewhere in the...

Activity 2 in this module examines How do objects become charged? An investigation of where the electrons come from and where they go, when atoms become charged.

A learning module that investigates a powerful tool to observe and manipulate atoms called the scanning tunneling microscope.

ScienceWorld.com offers a brief biography and image of Austrian physicist and inventor of wave mechanics, Erwin Schrodinger.

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses the properties of the atoms individually in relation to the main group elements of the Periodic Table.
