However, the modern periodic table of elements follow the law that, the properties of elements vary according to their atomic number and not by their weight. The elements of a Mendeleev's table were arranged in rows called periods and columns called groups. The chemical elements of the same group had similar properties In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. The most common way the periodic table is classified by metals, nonmetals, and metalloids. Periods in the periodic table In each period (horizontal row), the atomic numbers increase from left [ The periodic table is an arrangement of the chemical elements. It is organized based on chemical properties, atomic numbers and the configuration of electrons.
