WS 2.1 Protons, Neutrons, Electrons

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...

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...

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 periodic table worksheet, students answer ten questions about groups and families of the periodic table as well as atomic trends such as ionization energy and atomic radii.

In this electron dot structures handout, new chemists read about electron arrangement and how to draw electron dot diagrams. They complete a chart with the mass number, atomic number, isotope notation, number of neutrons, and Bohr...

The first two problems start with an explanation and guidelines for how to complete the electron configuration diagrams.  The following four problems give no advice, and the last six expect learners to draw the configuration for the ions.

The creator of this collection of chemistry slides is clever! Electron configuration is explained as, click-by-click, orbitals are displayed and then each is subsequently filled with the proper amount of electrons. After the progression,...

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. In this lesson plan, they compare materials made up of a single element and other materials...

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...
