ACTIVITY in Elements, Periodic Table, Review, Model of the Atom, Atomic Mass, Subatomic Particles. Last updated February 07, 2022.


In this activity, students will play an online game that quizzes their knowledge about the atomic structure of the first 20 elements on the periodic table. Students will be asked to identify different elements based on information related to subatomic particles, placement on the periodic table or from a provided Bohr model. This game has several options for students to choose from, and can be used to review content, or as a formative assessment.

Grade Level

Middle School and Elementary School

NGSS Alignment

This activity will help prepare your students to meet the performance expectations in the following standards:

  • MS-PS1-1: Develop models to describe atomic composition of simple molecules and extended structures.
  • Scientific and Engineering Practices:
    • Using Mathematics and Computational Thinking
    • Developing and Using Models
    • Analyzing and Interpreting Data


By the end of this activity, students should be able to:

  • Identify an atom given the number of protons, or electrons.
  • Identify an atom given the number of neutrons and the atomic mass.
  • Determine the corresponding element when provided with a Bohr model.
  • Use the periodic table to determine the identity of an element.

Chemistry Topics

This activity supports students’ understanding of:

  • Elements
  • Periodic Table
  • Subatomic Particles
  • Atomic Structure
  • Subatomic Particles
  • Model of the Atom
  • Atomic Mass


Teacher Preparation: 5 minutes
Lesson: 15-30 minutes



  • No safety precautions need to be observed for this activity.

Teacher Notes

  • This game was created by as part of Lesson 4.2: The Periodic Table. This is an online game version of the periodic card game made available as part of the 4.2 lesson.
  • Teachers can use lesson 4.2 from in its entirety or this game can be used separately as a review activity, or formative assessment.
  • When students first visit the website for the game, they will be presented with two game options. The questions in Game 1 ask students to identify elements based on information about subatomic particles. The questions in Game 2 are related to the Bohr model of the atom, and students will need to be able to interpret the Bohr model in order to answer the given questions.
  • Teachers can assign students to play just one of the two games available, or both depending on their preference and the relevance of the content.
  • In Game 1, students can choose from a 20-question game, a 50-question game, or a 100-question game.
  • In Game 2, students can choose from a 20-question game, a 40-question game, or an 80-question game.
  • Students will be given two chances to get each question right. When a question is answered correctly, students earn one point, and the card is removed from the deck. When a wrong answer is chosen, students are given a helpful hint.
  • The games are automatically timed, so students can play more than once and might be motivated to try to beat their original time.
