Como principal objetivo se tiene que, a partir del aprendizaje activo y significativo, los estudiantes puedan hacer accesible un sistema tan abstracto y complejo desde el trabajo en el aula en su saber hacer, para ello se utilizan cajas de huevo como material reciclable que representarán los orbitales y bolas de ping-pong para representar los electrones como modelo corpuscular; este modelo se aplica en las aulas de clase para explicar datos numéricos de la energía de ionización como propiedad periódica que se desea entender. Los modelos fueron bien asimilados para la muestra de estudiantes evaluados y permitió generar discusiones dentro del aula de clase, espacios argumentativos y descripción de modelos o predicción de modelos bajo una conceptualización didáctica grupal.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The electronic configuration diagrams are schemes that allow explaining some properties of the elements in the periodic table, considering the movement and filling of electrons in the orbitals according to the rules of Hund, to understand concepts at the electronic level such as electronegativity, shielding effect of electrons, ionization energy, and effective nuclear charge, among others. The main objective is that, from the active and meaningful learning, the students can make accessible such an abstract and complex system from the work in the classroom in their know-how, for this they use egg boxes as recyclable material that will represent the orbitals and ping-pong balls to represent electrons as a corpuscular model. This model is applied in classrooms to explain numerical data of the ionization energy as periodic property that one wishes to understand. The models were well assimilated for the sample of students evaluated and allowed to generate discussions within the classroom, argumentative spaces and description of models or prediction of models under a group didactic conceptualization.]]></p></abstract>
