Scholars build specific elements by creating a model of its atomic structure. Objects they can include are protons, nuetrons, electrons, orbits, clouds, charge, and mass number. Simulation ends with questions to challenge individuals'...

Protons and neutrons and electrons, oh my! Physical science scholars get hands-on with interactive atomic modeling. Starting with a simple helium atom, participants create and name ions, then build isotopes. Questions throughout the...

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

What's smaller than a kiwi seed? Atoms! Basic atomic structure is detailed for beginning chemists in a light-hearted animation. Protons and neutrons are explained as part of the nucleus, and so are electrons that encircle the nucleus....

Feeling a little uncertain about your materials for teaching the quantum mechanical model of the atom? Here is an interactive that will help! Chemistry and physics scholars alike will benefit from a simple resource that illustrates the...

Young mathematical scientists interact with protons and electrons in an atom to create a neutrally charged atom. They answer questions based on their findings throughout the interactive resource.

In this interactive Internet  assignment, physical science investigators answer 11 questions about the atom, the subatomic particles, and atomic structure. They can click on "Reveal Answer" to discover if they are correct. They also...

In this science:  atom quiz worksheet, students answer 10 true or false questions, not interactively, then scroll down to check their answers.

Shock your physical science class using this video to teach the basics of static electricity. Electricity is defined,and electrons are differentiated from protons on an atom model. The use of hydropower and wind are explained as ways of...

There are different types of radioactive decay, and alpha decay is when there are too many protons in a nucleus. Here is a simulation that shows alpha particles being emitted from a polonium nucleus. Learners see how radioactive decay...

In this chemistry worksheet, students read about atoms, their charges, and their parts; protons and neutrons. They examine how to determine atomic weight by looking at an example. They work online as they practice finding the atomic...

Changing the number of neutrons in an atom makes it an isotope, but it does not change the element. Pupils complete logic puzzles, matching isotopes with their unique number of protons, neutrons, and electrons. Either on paper or timed...

Explore how changing the numbers of protons, neutrons, and electrons affect the type of 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 your ideas!

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!

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.

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.

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...

This page is an exercise in relating the number of protons, electrons, and neutrons for an atom or monoatomic ion.

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

Build elements and molecules using neutrons, protons, and electrons. Choices include helium, carbon, oxygen, aluminum, water, and salt.

Learn how to read the periodic table of elements as you solve these Math questions about the number of protons, neutrons, electrons or nucleons in an atom of an element. You can choose how many questions to answer, and how complex they...
