How do protons stick together in a nucleus?

Perfect for reviewing atomic components, this activity simply consists of a large, easy-to-read chart of 11 elements. Chemistry learners fill in the missing element symbol, number of protons, neutrons, and electrons, the atomic mass and...

Up and atom! After labeling the parts of an atom, young chemists answer 16 diagram-based questions that deal with protons, neutrons, electrons, and atomic number.

In this atom worksheet, chemists learn how to determine the number of protons, neutrons and electrons in an atom using the atomic mass and atomic number. They complete a chart of the subatomic particles and use marbles to represent...

Although the focus of this instructional activity is the neutron, you cannot talke about them without also dealing with protons and electrons! Chemistry kids fill in a table of 14 elements, identifying the mass, atomic number, isotopic...

Discover the relationship between mass number, atomic number, and the makeup of the atom. The video instructor explains how to determine the number of each subatomic particle from the atomic and mass number. She demonstrates multiple...

Just because we can't see an atom doesn't mean we can't study it! The video examines the makeup of the atom. It explains the roles of the protons, neutrons, and electrons. 

High schoolers are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student...

Students research the element of carbon, its composition, and the importance of carbon to life on earth. Then they design model mobiles of carbon atoms to demonstrate their understanding of the configuration of protons, neutrons, and...

Explore and control the building blocks of atoms! Physical science superstars add and remove subatomic particles to create atoms and ions with an easy-to-use interactive. An alternate activity includes an assignment that focuses on the...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...
