| Summary, etc | The periodic table of elements shows only three columns and two separate rows for lanthanides and actinides called lanthanide and actinide series respectively. The newly discovered elements have already occupied the last row and last column of the table, which has the electronic orbital confi- guration, 7s2 5f14 6d10 7p6. After the discovery of two more new elements with atomic numbers 119 and 120, the third new element with atomic number 121, will have to be entered in the g-block series, according to the electronic orbital configuration theory, 7s2 5f14 6d10 7p6 8s2 5g1. Thus, in the present periodic table, such new g-series has to be written separately below the actinide series. Such a representation of elements would be quite confusing. Therefore, to avoid this and also to ensure the visibility of the ‘concept of inner orb itals like d, f, g, etc.’, a new and expanded form of the periodic table has been designed. This table is expected to accommodate all the new elements of higher atomic numbers and also give instant information on the electronic orbital structure of an element. |
