Periods are the rows. The reactivity or inertness of an atom solely depends on its number of Introduced in 1868, the term is used to express both the power of combination of an element in general and the numerical value of the power of combination. The more core electron shells an atom has, the larger the size of the atom, and the farther the valence electrons are from the nucleus, thus the valence electrons will experience less effective nuclear charge and will be easily lost. From the Bohr-Bury scheme, we find out the outermost shell of an atom can accommodate a maximum of 8 electrons and thus, It was observed that the elements, having a completely filled outermost shell (meaning zero valencies) show little chemical activity. The electron arrangement of an atom can be found out from its atomic number. Under standard conditions, atoms fill the inner shells first, often resulting in a variable number of electrons in the outermost shell.
