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...

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 configuration worksheet, students fill out a table with principle quantum numbers, the sublevels, the orbital and the number of electrons in each. They write electron configurations for given atoms as well as short cut...

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,...

How to determine electron configurations is the focus of this video. Sal shows students two different methods to find the electron configuration for the element, nickel. The first technique uses the periodic table, while second technique...

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...
