Which Element Am I? Mark as Favorite (18 Favorites)

ACTIVITY in Physical Properties, Elements, History, Periodic Table, Atomic Mass, Subatomic Particles. Last updated January 22, 2019.

Summary

In this activity, students will be challenged by a list of clues that describe 50 different elements from the periodic table. Using their own knowledge, or the help of the internet students will determine the identity of each element based on the clue provided.

Grade Level

High School

Objectives

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

  • Identify elements on the periodic table based on information about their physical properties.
  • Understand that every element has distinguishing characteristics that make it unique.
  • Differentiate between groups and periods on the periodic table as well as identify elements that belong to a particular family of elements.
  • Use information about atomic structure to identify an element.

Chemistry Topics

This activity supports students’ understanding of

  • Periodic Table
  • Elements
  • Physical Properties
  • History
  • Atomic Structure
  • Atomic Mass
  • Subatomic Particles

Time:

Teacher Preparation: Minimal

Lesson: 45 minutes

Materials

  • Student Handout
  • Periodic Table
  • Text Book (optional)
  • Internet (optional)

Safety

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

Teacher Notes

  • Many of these questions can be solved using just the periodic table. Some may require a basic information search. Teachers can determine if they would like to allow students to access the internet or use a textbook.
  • I suggest that students work in groups of two or three, however they can also work independently.
  • This activity can be used at the beginning of a unit on the periodic table, trends and/or atomic structure to challenge student’s prior knowledge. Alternatively, it can be used at the end of the unit as a cumulative assignment. In addition it can be edited for time, and information can be added or changed as needed.

For the Student

Lesson

Directions

There are (as of this writing) 118 elements on the Periodic table. Many are naturally occurring, some are synthesized. All have their own distinct properties and origins. Below is a list of clues for 50 different elements. You may use your book, internet and periodic table to find the names and symbols of the elements that match the clues below. Some are harder than others, but all are possible to solve, if you have patience!
