< Synthetic Elements >
Synthetic elements are unstable Chemical elements and they are not naturally found on the earth. These elements are synthesized (made)in the laboratory. All of them are unstable and radioactive in nature, which means they emit radiations and decay into other elements. Their discovery helped to fill the empty gaps in the periodic table, and they were later produced for research purposes.
There are 118 elements in the periodic table, out of which 89 are natural elements and the remaining are synthetic elements. Technetium (atomic number 43) was the first synthetic element discovered, that filled the mysterious gap between the elements, Molybdenum (atomic weight 42) and Ruthenium (atomic weight 44) in the periodic table. Promethium (atomic number 61), Astatine (atomic number 85), Francium (atomic number 87) and the transuranium elements constitute the synthetic elements. Transuranium elements are those elements whose atomic number is greater than Uranium (atomic weight 92). Here i have listed all the synthetic elements with their Atomic mass and Form also.
