Representación del sistema periódico: una tabla basada en tríadas
DOI:
https://doi.org/10.18270/rcfc.v13i26.1648Resumo
En este artículo presentaremos una representación del sistema periódico basada en dos
pilares fundamentales: las tríadas de número atómico y la concepción de los elementos
químicos como sustancias básicas. En la última década, la noción de tríada ha sido
rescatada y sugerida por Eric Scerri como posible criterio categorial para representar
la periodicidad química. Mediante esta representación, mostraremos como a través de
tríadas es posible reconstruir todas las relaciones entre los elementos que forman los
grupos del sistema periódico, sin apelar a las configuraciones electrónicas.
