The reason the periodic table is the shape that it is has to do with the electronic configurations of the elements. The periodic table is arranged so that all the elements in each period (row) have similar electronic configurations to the other elements in that period. That also often means that elements in the same group (column) show similar chemical reactivity. Electrons in atoms are arranged in different orbitals (named s, p, d, and âf).
The periodic table organizes every element we know of in a collocated manner. Advertisement The table arranges elements according to their atomic number, which is same as the number of protons or electrons they encompass.
