Glyph origin 1

Chemical element (edit)
Si Atomic number 14 硅 (guī)
Alternative names: 矽 (xī)
Classification data Period 3 Group 14 Block p-block Class metalloid
Previous: ← 鋁 (lǚ) (Al)
Next: 磷, 燐 (lín) (P) →

Phono-semantic compound (形聲 / 形声): semantic 石 (“stone”) + phonetic 圭 (guī).

Etymology

An orthographic borrowing from Japanese 硅(けい)素(そ) (keiso) (Wu, 2010); pronunciation from its phonetic part 圭 (guī) (ibid.), in turn from Dutch keiaarde (“silicon”). The usage of 矽 (xī) is dated in Mainland China as it is homophonous to 硒 (xī) "selenium" and 錫／锡 (xī) "tin". In Taiwan, these three words are not homophonous.

The 1932 ROC Ministry of Education's Principles of Chemical Nomenclature says:

硅由日名珪素孳演而成，因爲固體，故改王旁爲石。 [Classical Chinese, trad.]

硅由日名珪素孳演而成，因为固体，故改王旁为石。 [Classical Chinese, simp.]

From: 1932, 國立編譯館, 化學命名原則

Guī yóu rì míng guīsù zī yǎn ér chéng, yīn wéi gùtǐ, gù gǎi wáng páng wéi shí. [Pinyin]

硅 is derived and developed from the Japanese name 珪素 (けいそ, keiso). Considering Si is a solid substance, we hence convert the component 王 into 石.
