فهرست ریشه نام عنصرهای شیمیایی

عناصر شیمیایی جدول تناوبی در طول تاریخ نام‌های گوناگونی دریافت کرده‌اند.

این مقاله فهرستی از ریشه‌شناسی نام عنصرهای شیمیایی جدول تناوبی است.

پیشینه

در طول تاریخ شیمی، چندین عنصر شیمیایی کشف شده‌است. در قرن نوزدهم، مندلیف جدول تناوبی را فرموله کرد، جدولی که ساختار عنصرها را توصیف می‌کند. از آنجا که عنصرها در زمان‌ها و مکان‌های گوناگون، از دوران باستان تا به امروز کشف شده‌اند، نام آن‌ها از چندین زبان و فرهنگ گرفته شده‌است.

جدول

The word is derived (via Latin: beryllus and French: béryl) from the Greek βήρυλλος، bērullos، a blue-green spar، from Prakrit veruliya (वॆरुलिय)، from Pāli veḷuriya (वेलुरिय)؛ veḷiru (भेलिरु) or، viḷar (भिलर्)، "to become pale،" in reference to the pale semiprecious gemstone beryl. The word is ultimately derived from the Sanskrit word वैडूर्य vaidurya، which might be related to the name of the Indian city of Belur.
5	بور	B	زبان عربی، لاتین قرون وسطی، زبان آنگلو-نورمن، فرانسوی میانه، و انگلیسی میانه	بورق (buraq)		از عبارت لاتین بوراکس که خود از بوره از فارسی (عربی) آمده	از عبارت عربی بورق (buraq)، که ریشه در ماده بوراکس دارد. که احتمالاً ریشه در زبان فارسی و عبارت بوره (burah) دارد. بوره وارد عربی و سپس وارد زبان لاتین قرون وسطی شد و به شکل baurach، درآمد پس از آن وارد آنگلو-نورمن شد و به شکل boreis در آمد این عبارت در انگلیسی میانه به شکل boras، پذیرفته شد که ریشهٔ نام امروزی آن در انگلیسی به صورت "boron" (بور) است.
6	کربن	C	لاتین به واسطهٔ فرانسوی	carbone	زغال	لاتین کاربو	از عبارت فرانسوی کاربن، which in turn came from Latin carbō، which means "charcoal" and is related to carbōn، which means "a coal". (The German and زبان هلندی names، "Kohlenstoff" and "koolstof"، respectively، both literally mean "coal matter".) These words were derived from the زبان نیا-هندواروپایی base *ker- meaning heat، fire، or to burn.
7	نیتروژن	N	Greek via Latin and French	νίτρον (Latin: nitrum) -γενής (-genes)	native-soda begetter	descriptive	From French "nitrogène"، derived from Greek νίτρον γείνομαι (nitron geinomai)، meaning "I form/beget native-soda (niter)". Also used was azoth، from Andalusian Arabic al-zuq، from the Classical Arabic name of the element.
8	اکسیژن	O	Greek via French	ὀξύ γείνομαι (oxy geinomai)/oxygène	to bring forth acid		From Greek ὀξύ γείνομαι (oxy geinomai)، which means "Ι bring forth acid"، as it was believed to be an essential component of acids. This phrase was corrupted into the French oxygène، which became the source of the English "oxygen".

10	نئون	Ne	Greek	νέος (neos)	new		From Greek "νέος" (neos)، which means "new".
11	سدیم	Na	English	soda			From the English "بی‌کربنات سدیم"، used in names for رده:ترکیب‌های سدیم such as سدیم هیدروکسید، سدیم کربنات، and بی‌کربنات سدیم. Probably from Italian sida (or directly from Medieval Latin soda) "a kind of saltwort،" from which soda was obtained، of uncertain origin. The symbol Na is from the لاتین نوین noun natrium، derived from Greek νίτρον (nítron)، "natural soda، a kind of نمک (شیمی)" + Latin -ium. The original source is either the Arabic word نطرون natrun or the زبان‌های مصری word netjeri.

27	کبالت	Co	German	Kobold	evil spirit	German kobold	From German Kobold، which means "evil spirit". The metal was named by miners، because it was poisonous and troublesome (آلودگی and degraded other mined elements، such as nickel). Other sources cite the origin in the silver miners' belief that cobalt had been placed by "Kobolds"، who had stolen the silver. Some also think that the name may have been derived from Greek κόβαλος، kobalos، which means "mine" and which may have common roots with kobold، goblin، and cobalt.
28	نیکل	Ni	زبان سوئدی via German	Kopparnickel/ Kupfernickel	copper-coloured ore	descriptive	From the زبان سوئدی kopparnickel، meaning "copper-coloured ore"؛ this referred to the ore نیکلین from which it was obtained.

The Latin term، during the Roman Empire، was aes cyprium؛ "aes" was the generic term for copper alloys such as برنز). Cyprium means "قبرس" or "which is from Cyprus"، where so much of it was mined؛ it was simplified to cuprum and then eventually Anglicized as copper (Old English coper/copor).
30	روی	Zn	German	Zink	Cornet		From German Zink which is related to Zinken "prong، point"، probably alluding to its spiky crystals. May be derived from Old زبان فارسی.
31	گالیم	Ga	Latin	Gallia	Gaul (Ancient France)	جای‌نام	From Latin Gallia، which means گل (سرزمین) (Ancient France)، and also gallus، which means "rooster". The element was obtained as free metal by پل-امیل لکو د بویسباودران، who named gallium after France، his native land، and also، punningly، after himself، as Lecoq، which means "the خروس"، or in Latin، gallus. Gallium was called eka-aluminium by دمیتری مندلیف who predicted its existence.

51	آنتیموان	Sb	Greek? via Medieval Latin and انگلیسی میانه	ἀντί + μόνος (anti monos)؛ antimonium/ antimonie	various		Possibly from Greek ἀντί + μόνος (anti monos)، approximately meaning "opposed to solitude"، as believed never to exist in pure form، or ἀντί + μοναχός (anti monachos) for "monk-killer" (in French folk etymology، anti-moine "monk's bane")، because many early alchemists were monks، and antimony is poisonous. This may also be derived from the فرعون (مصر باستانian)، Antos عمون (expression)، which could be translated as "bloom of the god Ammo". The symbol Sb is from Latin name stibium، which is derived from Greek Στίβι stíbi، a variant of στίμμι stimmi (genitive: στίμμεος or στίμμιδος)، probably a loan word from Arabic or Egyptian sdm meaning "eyepaint". Littré suggests that the first form is derived from *stimmida، a hypothetical alternative حالت مفعولی of stimmi (the canonical accusative of the noun is the same as the nominative: stimmi). The Arabic word for the substance، as "mark" or "the cosmetic"، can appear as تحمیض، ثمود، وثمود، وثمود ithmid، athmoud، othmod or uthmod.

56	باریم	Ba	Greek via لاتین نوین	βαρύς (barys)	heavy	Greek چگالی	βαρύς (barys) means "heavy". The oxide was initially called "barote"، then "baryta"، which was modified to "barium" to describe the metal. همفری دیوی gave the element this name because it was originally found in باریتین، which shares the same source.
57	لانتان	La	Greek	λανθάνειν (lanthanein)	to lie hidden		From Greek lanthanein، "to lie (hidden)".
58	سریم	Ce	Latin	Ceres	grain، bread	astrological؛ mythological سرس	Named after the asteroid سرس، discovered two years earlier.
