Home Science Howmanyarethere 28 March 2011 4536 Views. There are 118 known chemical elements as of 2011.First element on the periodic table is Hydrogen the latest one is Ununoctium. The table contains 118 chemical elements whose discoveries have been confirmed. The first 94 are found naturally on Earth, and the rest are synthetic elements that have been produced artificially in particle accelerators.
A simple Google search would have sufficed. Number of elements in most of the periodic tables is 118 due to the perfect symmetry. However,the last properly named element is Copernicum which has atomic number of 112. The rest of the elements are just tentatively named. They will be properly named once there existence is properly proved.
