In theory, there are an unlimited number of elements....the ONLY reason we can only postulate 118 (and only confirm 103) is because of the physical limitations of the Universe....

Try to research the newest periodic table, I would state that today there are more than 118 elements :) Recently I have heard that the new one has come.. But, yes, try to find it :)

you're confusing possible elements vs discovered elements... (discovered meaning isolated in some obscure lab somewhere far away). there is no limit to the number of elements on the periodic table. only 118 or so elements have been "discovered" to date. see this table https://figures.boundless.com/9705/full/iodic-20table-20predictive.png btw.. often show the actinide / lanthanide series below the table for formatting (to fit on a 8 1/2 x 11 page) but it should really look like http://image.slidesharecdn.com/unit8powerpoint-100208160802-phpapp02/95/unit-8-periodic-table-of-elements-4-728.jpg?cb=1265645366
