How many different elements have scientists identified?
118
How are elements identified?
The individual elements are usually identified by the distinctive characteristics. They can be identified by touch and by sight.
How many identified elements does the periodic table show?
There are only 117 out of 118 elements on the Periodic Table that have been identified by research groups. Only 112 of the 117 have been recognized by the IUPAC. So, technically, there are 118 elements.
How much elements are discovered after Mendeleev in periodic table?
Mendeleev discovered the Periodic Law and produced his first Periodic Tables when about 65 elements were known, about 5 of which were poorly identified and later proved to be mixtures of similar elements. New elements were, at that time, being discovered at the rate of about one element per two years.Today, we know exactly how many elements there are, except that it is not totally clear how many artificial heavy elements it will be possible to prepare and characterize. We know 80 stable elements, another dozen or so that are radioactive and unstable, but can be found in nature, and another 20 or more that have been produced artificially. Some are long lived and can be prepared in large quantities and can be useful --e.g. plutonium and americium. Some others have only been prepared in quantities of a few atoms, and identified by a characteristic radiation signal on their decay.So the rough answer is about 30 elements have been discovered since 1871, and about another 22 have been artificially prepared.
