How many Elements are on the Periodic Table?

The modern periodic table (an updated version). All the elements up to element #118 have been given a real name.


Based on IUPAC standards, there are currently 118 elements on the periodic table. This is after four new elements were added in July of 2016. Scientists have now begun trying to find elements 119, 120 and 121. The discovered elements are, in order of atomic number: 


1 - H - Hydrogen

The Origins of the Periodic Table:


    The idea that all matter is made from a fundamental particle is a very old one. Elements such as gold, mercury, tin and lead were known for millennia although they weren’t always seen as such. The first scientific discovery of an element occurred in 1649 when Hennig Brand discovered Phosphorus. Many other scientists them jumped in and proved that certain elements existed. Once there were more than 60 elements, Russian Chemist Dmitri Mendeleev became of the first to develop a modern periodic based on the known trends of his day. Those fundamental trends are still those that are used today when organizing the modern periodic table. IUPAC was founded in 1919 to standardize the discovery of elements and provide universal names to them.

  2. Thanks for this beneficial article. There are 92 natural elements in the periodic table from hydrogen to uranium and currently, 26 transgenic elements have been created/observed. The natural elements mostly have stable isotopes and they all exist in nature. Each element is characterised by the number of protons in the nuclei of its atoms. Protons are large particles with a positive charge. Students can prepare physics exams with the help of online applications and websites. Physics games are also a good way to learn physics.
