selenium=عنصر السيلينيوم
ONLINE ETYMOLOGY DICTIONARY:
selenium (n.)
element name, Modern Latin, from Gk. selene "moon" (see Selene). Named by Berzelius (1818), on analogy of tellurium, with which it had been at first confused, and which was named for the earth. Despite the -ium ending it is not a metal and a more appropriate name selenion has been proposed.
Selene
moon goddess, from Greek selene "moon," related to selas "light, brightness, flame," from PIE root *swel- "to burn" (cf. Sanskrit svargah "heaven," Lithuanian svilti "to singe," Old English swelan "to be burnt up," Middle Low German swelan "to smolder"); related to swelter, sultry.
