Metallic uye asiri esimbi ehupfumi: tafura senhungamiro

Pfungwa yokuti "nesimbi" zvose pachangu zvakadaro kumiririra. Iron, sirivha, nendarama, mhangura, kutungamirira. Mazita aya anowanikwa nhau nguva dzose, vanhu vashoma vachange mibvunzo chii simbi. Kunyange zvakadaro, hazvina kurwadza kudzidza pamusoro chii zvacho kubva pakuona kwoMutsvene kemisiti uye yefizikisi, kana uchida kuyeuka hurongwa maonero enyika. Asi kukwana ruzivo panyaya iyi asingadi kukuvadzwa kudzidza pamusoro mamwe mapoka - vasiri simbi uye metalloids. Chii simbi uye asiri esimbi ehupfumi?

Kana ndangariro inobatanidzwa

Non-nesimbi seanotora husinganzwisisiki, kunyanya kune vaya vasingadi kurangarira chikoro kemisitiri, saka pfungwa pamusoro ehupfumi vasiri esimbi uye esimbi, ukuwo, anofanira aionekwa zvakashandurwa. Chokwadi kuti murege kurangarira, hapana nyadzi, uropi Zvakaoma kuchengeta mashoko mupfungwa kuti hakudi ose zuva. Saka, isu nyora ehupfumi vasiri esimbi uye vataure navo, kuti unyatsonzwisisa.

No kupisa, hapana magetsi

Non-nesimbi kuipa nesimbi kuitisa magetsi uye nokupisa. Naizvozvo, zvedongo nekomichiyakazara, chokutanga, anobata kupisa nani kupfuura simbi, uye chepiri mukana kupisa maoko enyu pamusoro mug of zvishoma zvikuru pane murwi simbi Mug. Uye yeuka, kuchengeteka ringakweva kubva kunobva njodzi munhu haagoni kuva anoshandiswa simbi zvinhu. Asi muti unogona kushandisa, carbon vemiti - nonmetal. The pfuma nesimbi - kuita kutira zvakanaka esimbi ehupfumi zvinosanganisira yakaderera conductivity.

Fragility kana plasticity

zvinhu wakachena nevasiri nesimbi kazhinji pfava kana kazhinji kazhinji zviripo hwakasimba neHurumende upfu fomu. Metal nokuchengetedza, unogona kukanganiswa tembiricha, maturusi uye chinonyanya kujairika muchando chimiro (shandisa unhu iri foundry mubhizimisi). Non-nesimbi regai kupatsanurwa. Non-nesimbi kazhinji, kunyange kana zvaitika muchimiro zvidimbu, uchine kamari arambe achirema uye kazhinji dziri porous.

Table somunhu mepu yacho

Kana "enda" riri periodic table kubva kuruboshwe kuenda kurudyi: uchaona kuti asiri esimbi ehupfumi vari chakaiswa kubva kuruboshwe kuenda kurudyi. Nehelium - chikuru "Excellent vasiri simbi." Asi kana ukaenda pasi petafura, esimbi ehupfumi kuti kupera. Metals uyewo kuva zvechisimba sezvo imi aburuke pasi periodic table. Saka, periodic table anogona nehasha zvokufungidzira ehupfumi nyore zvinhu, zvinosanganisira kwemaatomu zvikuru zvinhu. Fuma "pakati" dzinonzi metalloids uye anoshandiswa kakawanda zvemagetsi ouinjiniya sezvo semiconductors.

Kushandiswa vasiri simbi

General zvezvinotaurwa vose vasiri simbi vasingadaro. Mumwe ane "specialization" yayo, sezvo asiri esimbi zvinhu - siyana. Inert magasi inoshandiswa panze kushambadzira, selenium - nokuti toners ari kudhindwa indasitiri, nesarufa iri mutambo. Tinogara nevanhu muupenyu hwavo hwezuva nezuva pamwe zvinhu, acho vasiri simbi nomukaka.

Saka, vasiri esimbi ehupfumi, kufanana simbi, zvinogona nezvacho periodic table. Uye mapatani aya anonakidza zvikuru, nokuti tafura muzvitoro vachiri vazhinji vanzika zvakavanzika kuti vakwanise masayendisiti kutarisa kure kare, uye zvichida mune ramangwana. Kunyanya kufarira remangwana metalloid.
