Siliva ndi yofanana ndi mawonekedwe ake akuthupi ndi mankhwala kwa oyandikana nawo awiri ofukula mu gulu 11 la tebulo la periodic, mkuwa ndi golidi. Ma electron ake 47 amakonzedwa mwadongosolo, mofanana ndi mkuwa ndi golidi; gulu 11 ndi limodzi mwamagulu ochepa mu d-block yomwe ili ndi makonzedwe a elekitironi osasinthika. Kusintha kwapadera kwa elekitironi, komwe kumakhala ndi elekitironi imodzi m'gulu laling'ono kwambiri lokhala ndi d subshell yodzaza, kumapangitsa zinthu zambiri zachitsulo zasiliva.

Siliva ndi chitsulo chofewa kwambiri, chodumphira komanso chosinthika, ngakhale ndi chocheperako pang'ono kuposa golide. Siliva imayang'ana mu latisi yokhala ndi nkhope yokhala ndi ma kiyubiki okhala ndi nambala 12 yolumikizana, pomwe ma elekitironi a 5s okha amachotsedwa, mofanana ndi mkuwa ndi golide. Mosiyana ndi zitsulo zokhala ndi ma d-zipolopolo zosakwanira, zomangira zachitsulo mu siliva zilibe mawonekedwe ogwirizana ndipo ndizofooka. Kuwonetsetsa uku kukufotokozerani kuuma kochepa komanso kutsika kwakukulu kwa makhiristo amodzi a siliva.


Siliva ali ndi zonyezimira zoyera zachitsulo zonyezimira zomwe zimatha kupukuta kwambiri, zomwe zimakhala zodziwika kwambiri mwakuti dzina lachitsulocho lasanduka dzina la mtundu.[8] Mosiyana ndi mkuwa ndi golidi, mphamvu yofunikira kuti isangalatse electron kuchokera ku gulu lodzaza d kupita ku gulu la sp conduction mu siliva ndi lalikulu mokwanira (mozungulira 385 kJ / mol) kuti silikugwirizananso ndi kuyamwa m'dera lowoneka la sipekitiramu, koma makamaka mu ultraviolet; motero siliva sichitsulo chachikuda.[8] Siliva wotetezedwa ali ndi kuwala kowoneka bwino kuposa aluminiyamu pamafunde onse atali kuposa ~ 450 nm. Pamafunde afupikitsa kuposa 450 nm, kuwunikira kwa siliva kumakhala kotsika kuposa kwa aluminiyamu ndikutsika mpaka ziro pafupi ndi 310 nm.


Mgodi wa siliva

Migodi ya siliva ndiyomwe imachotsa siliva ndi migodi.
Siliva imapezeka mumtundu wachilengedwe kawirikawiri ngati ma nuggets, koma nthawi zambiri imaphatikizidwa ndi sulfure, arsenic, antimony, kapena chlorine komanso m'matanthwe osiyanasiyana monga argentite (Ag2S), chlorargyrite ("nyanga siliva," AgCl), ndi galena (a miyala yamtovu nthawi zambiri imakhala ndi siliva wambiri). Monga siliva nthawi zambiri imapezeka molumikizana ndi izi kapena kusakaniza ndi zitsulo zina monga golide, nthawi zambiri imayenera kuchotsedwanso kudzera mu kuphatikiza kapena electrolysis.
Migodi ya siliva yakhala ikuchitika kuyambira kalekale. Monga siliva ndi chitsulo chamtengo wapatali chomwe chimagwiritsidwa ntchito pa ndalama zachitsulo, migodi yake nthawi zambiri imakhala yopindulitsa. Monga momwe zilili ndi zitsulo zina zamtengo wapatali monga golide kapena platinamu, miyala ya siliva yomwe yangopezedwa kumene yachititsa kuti anthu ogwira ntchito m’migodi apeze chuma chawo. M’zaka mazana aposachedwapa, ma depositi aakulu anapezedwa ndi kukumbidwa ku America, kusonkhezera kukula ndi chitukuko cha Mexico, maiko a Andes monga Bolivia, Chile, ndi Peru, komanso Canada ndi United States.
