Properties of Representative Elements
Recollect from the former analysis of electron configurations that Hydrogen, Lithium and sodium all ended with s1 configuration. Whenever we look at other representative chemical element therein grouping we will have that the relation proceeds on down the periodic table. All of a common elements in group IA end in s1 configuration for their electron configuration.
H1s1H1s1
Li2s1Li2s1
Na3s1Na3s1
K4s1K4s1
Rb5s1Rb5s1
Cs6s1Cs6s1

( arranged the elements by increasing atomic mass and noticed that elements with similar properties appeared at regular intervals or periods. Mendeleev's table had two problems: ... When grouped by properties, most elements had increasing atomic masses, but some were out of order.)
