Answer
When the elements are arranged in a periodic table in order of increasing atomic number, the elements end up arranged in columns, called groups, and rows, called periods. A pattern is revealed with this arrangement, known as the periodic law: When elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties. Therefore, when we go from one period to the next one, we will notice that the properties of the former will be repeated in the latter. Consequently, elements in the same columns have similar properties.
