History	The element Helium was discovered by P. Janssen and N. Lockyer in year 1868 in Sweden and United Kingdom. Helium derived its name from the Greek word helios, meaning 'sun'.	The element Antimony was discovered by Arabic alchemist in year ca. 800 AD in one. Antimony derived its name from the Greek anti, 'against', and monos, 'alone' (stibium in Latin).
