Ko te silicon he matū matū, he mārō, he pakaru hoki, he karakara, he karakara hoki. He mema o te rōpū 14 i roto i te ripanga auau: kei runga ake i a ia te waro; kei raro iho i a ia te germanium, te tini, me te mata. He āhua kore mahi. Nā tōna pānga matū nui ki te hāora, kāore i taea e Jöns Jakob Berzelius te whakarite i a ia i te tau 1823 i te tuatahi, ā, i whakamōhio i a ia i roto i te āhua parakore. Ko ōna tohu rewa, me te matao o te 1414 °C me te 3265 °C, ko te tuarua-nui rawa i roto i te katoa o ngā whakarewa me ngā pūmārō kore, ka whakanuia e te boron anake. Ko te silicon te mea tuatoru tino noa i roto i te ao whānui, engari ko te nuinga o ngā momo pūmārō i roto i te ao whānui, engari ko te germanium, te tini, me te matao i raro i a ia.
