In 1913 Sir Henry Moseley discovered There are 18 groups and 7 periods in the that elements positions in the periodic modern periodic table. Long Form of Periodic Table This periodic table is based on the electronic configuration of elements. There are 118 elements have been identified. A block of the periodic table of elements is a set of adjacent groups. The respective highest-energy electrons in each element in a block belong to the same atomic orbital type. Each block is named after its characteristic orbital; thus, the blocks are: s-block, p- block, d-block and f-block 272
