First Twenty Periodic Table Elements
Lesson Plan Reference
Grade Level 6-12
Difficulty Level 4 (Difficult / Complex)
Type of Assignment Individual or Group
Have your students create their own periodic table by researching the first 20 elements and completing a storyboard.
Students will learn the symbols of the first 20 elements. It is important to remind them that if the symbol for an element has two letters, then the first letter will be capitalized and the second will be lowercase. For example, the symbol for helium is He, not HE or he.
The elements are arranged by order of atomic number (which is the number of protons and electrons), not the atomic mass.
Students can produce the electron arrangement diagrams using the smart atom diagram item. The smart atom item is pre-populated in the template, but search for “atom” to retrieve another. Electrons are arranged in shells and fill the shells from the shell closest to the nucleus to the one furthest away. Different shells can hold different numbers of electrons. The first shell only holds two electrons, the second and third shells hold 8 electrons (for the first twenty elements), and the fourth shell holds 18 electrons.
|Element||Symbol||Atomic Number||Atomic Mass||Number of Protons||Number of Neutrons||Number of Electrons||Number in 1st Shell||Number in 2nd Shell||Number in 3rd Shell||Number in 4th Shell|
Students will add a visualization to the “Uses” cell. This could be a picture from Photos for Class of the element or an image displaying the use of the element. Some elements are more difficult than others, so your students may need to get creative.
This is a great activity to check concept understanding at the end of teaching the elements and periodic table topic. Alternatively, have your students complete this activity at the start of the topic and use the resource they made as a personalized study guide. You can make this less challenging for students by giving them more information at the start or by asking them to include less information. For example students could just include the symbol and the atomic number.To stretch your most able students, get them to research properties and uses for each of the first 20 elements and they could then include this information on their storyboards.
Please note in this activity I have used the atomic mass of the most abundant isotope for each element. You may find on some periodic tables, the average atomic mass is listed.

You are going to create a chart detailing key information about the first 20 elements.
- Click "Use this Template" from the assignment.
- First find the symbol and names on the first 20 elements and use Textables to write them in each cell in the correct order. Remember if an element has two letters for its symbol, the first letter will be a capital and the second will be lowercase.
- Then research the information to include in the blue fact box. You should include
- The atomic number
- The atomic mass
- The number of protons
- The number of neutrons
- The number of electrons
- Create the electron arrangement for each element using the smart atom diagram. Remember the first shell can hold 2 electrons, the second and third can hold 8, and the fourth shell can hold 18.
- Finally add a visualization to the cell to represent the element. This could be an image what it looks like or what it is used for.
- Save and submit your storyboard. Make sure to use the drop-down menu to save it under the assignment title.
