what is periodicity​

Sagot :

Periodicity refers to the recurring trends that are seen in the element properties. These trends became apparent to Russian chemist Dmitri Mendeleev (1834–1907) when he arranged the elements in a table in order of increasing mass. Based on the properties that were displayed by the known elements, Mendeleev was able to predict where there were "holes" in his table, or elements yet to be discovered.
