WS 2.1 Protons, Neutrons, Electrons

Chemsitry aces learn that protons are located in the nucleus and the number of protons in the nucleus determines the atomic number of an element. For this lesson, they compare materials made up of a single element and other materials...

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.

Perfect for reviewing atomic components, this worksheet 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...

Emerging chemists complete the table of electron levels, write electron configurations, and draw Lewis structures for a variety of atoms on this worksheet. Though there is a note about accessing a classroom website on the upper right...

Young scholars discuss how small they must cut something before it is no longer fundamentally the same. An online activity challenges and engages pupils in learning about the periodic table. Two hands-on activities cover elements and...

Although the focus of this worksheet 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 symbol, and...

Before determining which electrons are available for reactions, scientists identify each atom's electron configuration. An informative video from Socratica's chemistry playlist includes how to write electron configurations. It explains...

What does an atom look like? The instructor in a tutorial video models how to use the periodic table to determine the number of subatomic particles. He then uses the number of electrons to create an orbital diagram. Finally, Groves...

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...

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'...
