La tabla periódica de los elementos químicos
El año 2019 ha sido declarado por la ONU como el Año Internacional de la Tabla Periódica de los Elementos Químicos. La tabla periódica es uno de los pilares esenciales en los que se apoyan la química y la ingeniería química, pero también lo hacen la arqueología, astronomía, biología, bioquímica, ciencia de materiales, ciencia medioambiental, física, geología, paleontología y todas las ingenierías. La tabla periódica es el icono de la ciencia y la tecnología y una de las imágenes más fácilmente reconocibles de nuestra civilización. Ya lo expresó John Emsley: “Cualquier civilización inteligente de otra galaxia tiene una tabla periódica muy parecida a la nuestra: es un icono universal en el sentido más amplio”.
