| Abstract | Selenium is a member of the group 16 elements (O, S, Se, Te and radioactive Po), collectively known as chalcogens. Selenium is a non-metal with the symbol Se and has an atomic number 34. It was discovered in 1817 by J. J. Berzelius in the reddish deposits that were formed in the lead chambers at his sulfuric acid plant at Gripsholm in Sweden. He named the element selenium in the honour of Greek Goddess Selene, meaning moon. The physical and chemical properties of selenium are intermediate between those of sulfur and tellurium. Elemental selenium exists in various allotropic forms, of which three are generally known, namely two red allotropes of puckered Se8 rings which changed on heating to the more stable grey or black trigonal selenium, which is made up of helical Sen chains. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
