Origen de la Tabla Periódica
Se denomina tabla periódica a la representación de los elementos químicos de una manera ordenada, en grupos y periodos propuesta por el Químico Dmitri Mendeleiev (1834-1907). En 1869, Mendeléyev ordenó los elementos que se conocían hasta la fecha en forma de una la tabla donde se repetían propiedades en grupos, cuando le explicaba a sus alumnos con unas cartas que llevaban anotados el peso atómico y varias propiedades químicas.
Cuando se ordenaban de manera creciente en el peso atómico resultaban que los elementos de un mismo grupo mostraban propiedades químicas similares.
Elementos ordenados por número atómico
¿Como varía el radio atómico?
En la siguiente tabla se indican los valores de los radios de van der Waals y covalentes para todos los elementos de la tabla periódica.[1]
