Chapter 3: Atoms: The Building Blocks of Matter

Atomic Theory

Atomic Theory: The Early Days – history of atomic theory from the turn of the 20th century, and a simulation of hydrogen and helium atoms.

(Main Idea: Atoms can be subdivided into smaller particles.)

Atomic Theory: Ions, Isotopes, and Electrons – description of ions, isotopes, and electron shells, with animated simulations.

(Main Idea: All atoms of an element must have the same number of protons, but no neutrons; Atoms contain positive and negative particles.)

Atomic Structure

Tutorial on Atomic Structure – brief interactive tutorial along with questions to test your knowledge.

(Main Idea: Atoms can be subdivided into smaller particles; Atoms have small, dense, positively-charged nuclei.)

Build an Atom – an interactive activity in which you build atoms by adding protons, neutrons, and electrons to the model, then play the game to see how much you know!

(Main Idea: Atoms can be subdivided into smaller particles; Atoms have small, dense, positively-charged nuclei.)

Isotopes and Atomic Mass – learn about isotopes and the average atomic mass of an element by creating your own isotopes.

(Main Idea: All atoms of an element must have the same number of protons, but not neutrons.)

Models of the Hydrogen Atom – scientists discovered they could predict the structure of atoms by shooting light at them in a spectrometer. Try it yourself to experiment!

(Main Idea: The radii of atoms are expressed in picometers.)

Atomic Structure Jeopardy – answer questions from the challenge board to score points.  Play alone or challenge a friend to show how much you know about atomic structure.

Atomic Structure Hangman – play the classic game using atomic structure terms.

(Main Idea: Atoms can be subdivided into smaller particles; Atoms have small, dense, positively-charged nuclei.)

Atomic Interactions

Interactive activity to explore the interactions between combinations of atoms in terms of potential energy and distance between atoms, including total force and component forces such as Van der Waals and electron overlap.
