Chemical Elements and its Atomic Number and Symbol

The elements are the basic units of all types of matter. In 1800, only 31 elements were known. By 1865, the number of identified elements had more than doubled to 63. At present 118 elements are known. Of them, the recently discovered elements are man-made.

The construction of Period Table is attributed to Dmitri Ivanovich Mendeleev (1834-1907). His great textbook “Principles of Chemistry” led Mendeleev to propose the Periodic Law and to construct his Periodic Table of elements.
