Pravin Rajagopal: Hi Xome, So far they have found only 109 elements in periodic table. I have never heard a word called anti social element.When I was interacting with the senior director of Human resources Gayathri of Xome India she used a word called anti social element. As I trust more on science and technology, I started researching both the Mendeleev periodic table and modern periodic table. Finally I found there is nothing called anti social elements. Finally I found that there is no ambiguity on her about the fact that pure substances->elements->compounds->atoms->molecules->molecules->Ions.
