Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Silicon chinhu chemakemikari chine chiratidzo Si uye nhamba yeatomu 14. Iyo yakaoma uye yakapfava crystalline solid ine bhuruu-grey metallic lustre; uye ndeye tetravalent metalloid uye semiconductor. Iyo inhengo yeboka 14 mu periodic table: kabhoni iri pamusoro payo; uye germanium, tini, uye mutobvu zviri pasi payo. Hazviiti kuti zvinhu zvichinje. Nemhaka yokuwirirana kwayo kukuru nemakemikoro neoksijeni, kwakanga kusati kuri kutozosvikira muna 1823 apo Jöns Jakob Berzelius akatanga kukwanisa kuigadzira nokuirondedzera muchimiro chakachena. Iyo inonyunguduka uye inopisa mapoinzi e1414 °C uye 3265 °C zvichiteerana ndiyo yechipiri-yakakwirira pakati pese metalloids uye nonmetals, ichipfuura chete ne boron. Silicone ndiyo chinhu chechisere chinonyanya kuwanika muchadenga maererano nehuremu, asi kashoma zvikuru kuti chiwanikwe sechinhu chakachena muchikanda chePasi. Inonyanya kugoverwa mu guruva, jecha, mapuraneti, uye mapuraneti semhando dzakasiyana-siyana dze silicon dioxide (silica) kana silicates. Inopfuura 90% yepasi rose inoumbwa nemaminerari e silicate, zvichiita kuti silicon ive chinhu chechipiri chakanyanya kuwanda mupasi rose (inenge 28% nehuremu) mushure meokisijeni.  Mubvunzo: Chii chiri nhamba yeatomu yesilicon?
