The elements that are presently known and naturally occur elements has to be identified. Concept introduction: Element that means a fundamental substance that can’t be chemically changed or broken into anything simpler is called elements. The periodic table: Each element is identified through a one- or two-letter symbol and it is characterized by an atomic number . Let us consider the periodic table begins with hydrogen. 118 elements are presently known. About 90 elements occur naturally. The 14 elements beginning with Lanthanum ( La to Lu ) and the 14 elements beginning with Actinium ( La to Lr ) are pulled out. Elements are organized into 18 vertical columns (groups) and 7 horizontal rows (periods). The two groups on the left is s-block elements. The six on the right is known as main group’s elements. The ten in the middle is known as transition metals and finally the 14 elements beginning with Lanthanum ( La to Lu ) and the 14 elements beginning with Actinium ( La to Lr ) .
