Dobereiner
if the periodic table had not invented the chemical Dobereiner not have been able to show the relationship between the atomic mass of certain elements and their properties -
Period: to
triads
Dobereiner would not have been able to organize some elements in triads, considering its properties -
Chancourtois
Chancourtois not have been able to demonstrate the existence of periodicity between elements found until then -
law of octaves
Chancourtois the geologist and the chemist Newlands, had not been able to announce the law of octaves: the properties are repeated every eight elements -
atomic volume
Meyer could not bring out the frequency having certain atoms with respect to its volume -
first periodic table
Mendelev not have been able to present his first periodic table where the periodicity of the elements showed -
X ray
Moseley had not generated x-rays could not arrange the atoms in the periodic table according to their atomic number Z -
electronic structure
Chaverri would not have been able to present the version of the periodic table based on the electronic structure of the elements -
groups A and B
Alfred Werner could not have made their contribution to separate the elements of the periodic table into two groups A and B
