Elements were arranged in the periodic table based on their atomic structure and properties. The periodic table is organized in rows and columns, with elements in the same column having similar properties due to their similar electron configurations. The rows are arranged in order of increasing atomic number, which is the number of protons in the nucleus of an atom. The periodic table is divided into metals, nonmetals, and metalloids based on their physical and chemical properties. The arrangement of elements in the periodic table allows scientists to predict the behavior and properties of elements and their compounds.

Elements are arranged in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups. Elements in the same group have similar chemical properties. This is because they have the same number of outer electrons and the same valency
