Una propuesta para el tratamiento del enlace químico en el segundo ciclo de educación secundaria obligatoria

Abstract

El enlace químico es considerado como elemento organizador dentro de la Química y por tanto su aprendizaje en educación secundaria es fundamental para la comprensión del cuerpo epistemológico de dicha ciencia. En este trabajo se propone una unidad didáctica para 4º ESO en la que, a partir de la observación de las propiedades físicas de las sustancias, se busca que los alumnos construyan un modelo de enlace químico que permita explicar tales observaciones, utilizando el concepto de electronegatividad como elemento unificador y a la vez diferenciador de casos particulares de enlace químico.
