A Periodic Table Logic Problem Worksheet

A Periodic Table Logic Problem

Purpose: In this activity you will use a set of clues to identify a set of unknown

elements in a periodic table. The elements are the elements with atomic numbers

1-20 and 31-36. A letter of the alphabet is used to represent each unknown

element. The letter designation is not related to an element’s chemical symbol.

Each clue refers to a property of an element or a relationship an element has to

other elements in the periodic table. Along with logic and knowledge of

properties, you will use the periodic trends to solve the puzzle.

Grade: Neatness and completeness count.

Procedure: Use the following trend clues to place the elements in their proper

places on the provided periodic table. Try to identify the elements with direct

clues first. For example, B is a direct clue because it identifies only one element.

Group 1 Group 2 Group 13 Group 14 Group 15 Group 16 Group 17 Group 18
