Solution
The periodic table is an organized arrangement of the chemical elements based on their atomic number, electron configuration, and recurring chemical properties.
The modern periodic law states, "The physical and chemical properties of elements are a periodic function of their atomic numbers."
The alkali metals are kept in group 1 (IA) and halogens are kept in group 17 (VIIA) in the modern periodic table.
