Find out if you know enough about atoms to build them. The goal of the activity is to build an atom of a particular element by dragging the correct numbers of neutrons, protons and electrons into the atom.

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test how the ideas work!

A video and a short quiz on the parts of an atom, the periodic table, and molecules.

Explore how changing the numbers of protons, neutrons, and electrons affect the type of atom.

In this interactive activity from ChemThink, students will take a closer look at atomic structure, properties, and behaviors. Includes background reading material and discussion questions.

Identify the basic structure of atoms, the building blocks for all matter.

Kids learn more about the science of the atom. Electrons, neutrons, and protons make up the smallest bits of matter.

Explains the basics of atomic structure, from simple definitions to information about quantum theory. Accurate and helpful basics whether or not you need the more advanced information.

This lesson will illustrate that an atom is mostly empty space and has a positively charged, massive core (containing both protons and neutrons called the nucleus) surrounded by negatively charged electrons. It is 2 of 3 in the series...

This lesson will explain that electrons are negatively charged particles with negligible mass and are found in pairs in orbitals surrounding the nucleus of an atom. It is 3 of 3 in the series titled "Subatomic Particles: The Electron."

[Free Registration/Login Required] Build your own helium atom and make sure it has the correct number of protons, electrons, and neutrons on this site. Site also includes a small quiz on the topic.

This activity serves as an introduction to chemistry, and can be used to help students draw a two dimensional image of the atom.

The three basic particles that make up atoms are defined and illustrated.

This lesson will explain that protons are positively charged particles having a mass of one amu and are found in the nucleus of the atom. It is 2 of 3 in the series titled "Subatomic Particles: The Proton."

A choice menu assignment where young scholars select between several extension activities that help understand the structure of the atom.

Take a look at the parts of an atom and learn about its properties.

[Free Registration/Login Required] This flipchart defines the parts of the atom. It uses Activotes for assessment.

[Free Registration/Login Required] This flipchart was converted from Power Point and is used to introduce the history and concept of the Atom.

Introduces learners to atomic models of the past and present, focusing on the orbital model and an explanation of its basis. Learners then have the opportunity to "make an atom" and contrast it with an ion, followed by an isotope. The...
