The periodic law states that; When elements are arranged in order of increasing atomic number, there is a recurring pattern to their physical and chemical properties.

Explanation:

The periodic table is a table of elements derived from the periodic law that arranges elements into columns known as groups and rows known as periods. Elements in the same group or family share similar chemical characteristics. For example, potassium, sodium, and lithium belong to group 1 family and, therefore, share similar chemical properties. Elements in the same period have the same features, such as they have the same number of energy levels. For instance, elements in period 3 have three energy levels in their atoms.
