pattern of repeating order is called periodicity. In the mid-1800s, Dmitri Mendeleev, a Russian chemist, noticed a repeating pattern of chemical properties in elements.
Mendeleev arranged the elements in order of increasing atomic mass, to form something that resembles the modern periodic table. He was even able to predict the properties of some of the then-unknown elements. Later, the elements were rearranged in order of increasing atomic number

a thing which repeats itself after certain interval is called periodic and it this behaviour is termed as periodicity it is the similarity in the outer electronic configuration which gives rise to the periodicity in properties of elements
