Question

though elements are arranged in the increasing order of their atomic number, the real base of modern periodic table is electronic configuration-Evaluate

Answer 1

Elements are organized by period and group, with the period corresponding to the principle energy level, and the group relating to the extent the subshells are filled.

The properties of an atom relate directly to the number of electrons in various orbitals, and the periodic table is much like a road map among those orbitals such that chemical properties can be deduced by the position of an element on the table.

The electrons in the outermost or valence shell are especially important because they can engage in the sharing and exchange that is responsible for chemical reactions.
