The number of protons in the atom of an element determines its place in the Periodic Table. The number of electrons in an atom is the same as the number of protons. These electrons are arranged in shells or 'energy levels' around the...

This lesson focuses on the structure of atoms. All substances are made from atoms. Each atom is made of a nucleus - containing protons and neutrons - surrounded by electrons. It provides a link to an assessment.

Students explore the periodic table and learn the basic information given for elements: the name, symbol, atomic number, and atomic mass for each element.

An atom is made of three parts - protons, neutrons, and electrons. Here you can explore these different parts.

This lesson plan explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. Young scholars think about how atoms and molecules can influence new...

"The Phantom has provided you with a simulated spectroscopy of an Atom! Amuse the Phantom by observing the spectroscope and you'll learn more about the Atom." Observe and review the structure of the atom.

Fun and interesting illustrated information on atoms including composition, elements, and history.

Describes the structure of an atom and the characteristics of the electrons, neutrons, and protons inside it. Includes some interesting facts about atoms.

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...

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...

Investigate the forces of electrons and protons in this experiment with electrostatic charges.
