Cov metalloids yog ib pawg ntawm cov ntsiab lus nyob rau hauv lub sij hawm lub rooj. Lawv yog nyob mus rau sab xis ntawm lub post-transition hlau thiab rau sab laug ntawm cov non-metals. Metalloids muaj qee yam khoom sib xws nrog cov hlau thiab qee qhov sib xws nrog cov hlau tsis muaj hlau.

Ua kom pom qhov no, puas muaj 7 lossis 8 metalloids?

Txawm hais tias tsis muaj qhov tshwj xeeb, lub sijhawm tseem nyob hauv siv hauv cov ntaub ntawv ntawm chemistry. Lub sixcommonly lees paub metalloids yog boron, silicon, germanium, arsenic, antimony, thiab tellurium. Tsib lub ntsiab lus tsis tshua muaj kev faib tawm: carbon, aluminium, selenium, polonium, thiab astatine.

pawg twg yog metalloids nyob rau hauv? Pawg 13–16 ntawm lub periodic table muaj ib los yog ntau tshaj metalloids, ib Ntxiv rau cov hlau, nonmetals, orboth. Pab pawg 13 hu ua boron pab pawg , thiab boronis nkaus xwb metalloid hauv qhov no pab pawg . Lwm tus pab pawg 13 lub ntsiab yog hlau. Pab pawg 14 hu ua thecarbon pab pawg.

Ib yam li ntawd, koj yuav ua li cas txheeb xyuas lub metalloid?

Txoj hauv kev zoo tshaj plaws los txiav txim siab yog tias tsis paub lub ntsiab lus yog a Metalloid yog los ntawm kev tshuaj xyuas yog tias muaj cov yam ntxwv ntawm cov hlau thiab cov hlau tsis muaj hlau tuaj yeem pom, yog tias ob qho tib si ces koj feem ntau yuav muaj Metalloid keeb.

Tsuas muaj xya lub ntsiab lus cais:

  1. Boron.
  2. Silicon.
  3. Germanium.
  4. Arsenic.
  5. Antimony.
  6. Tellurium.
  7. Polonium.

Dab tsi yog metalloid hauv chemistry?

Metalloid , a tshuaj lub caij nrog cov khoom nruab nrab nruab nrab ntawm cov hlau thiab nonmetals. Feem ntau suav hais tias raws li kev faib tawm no yog cov tshuaj Cov ntsiab lus boron, silicon, germanium, arsenic, antimony, thiab tellurium.
