Abstract

An important part of the high school chemistry program is the topic of periodic classification and periodicity. We have observed that one of the obstacles for the study of the matter is the new vocabulary necessary to initiate this work. Our students have to understand that the periodic classification is an orderly way of presenting the elements and its properties, they compare the table with other classification systems that they already know, nevertheless for the average student it is difficult to deduce or predict properties with periodic classification. As an example of this concept, we can point out the electronic configuration, atomic radii, oxidation state, and valence number.

In order to facilitate the learning-teaching process of this topic in high school level, we stimulate the class to play with the periodic table, to get familiar with the general concepts of periodicity. We started our work dealing with the most common elements in each group. Chemical Elements Bingo (CEB) is a game we designed to teach periodic classification.
