A metalloid yog ib lub ntsiab ntawd muaj zog uas yog nruab nrab ntawm cov hlau thiab nonmetals. Metalloids kuj tseem hu ua semimetals. Nyob rau hauv lub sij hawm, lub cov ntsiab lus xim daj, uas feem ntau ciam teb rau txoj kab stair-step, suav tias yog metalloids.

Ua raws li qhov no hauv kev txiav txim siab, koj yuav txiav txim siab li cas yog tias lub ntsiab lus yog metalloid?

Txoj kev zoo tshaj plaws ntawm kev txiav txim yog ib tug tsis paub Lub ntsiab yog Metalloid yog los ntawm kuaj yog tias txhua tus yam ntxwv ntawm cov hlau thiab cov hlau tsis muaj hlau tuaj yeem pom, yog ob leeg yog ces koj feem ntau yuav muaj ib Metalloid element.

Tsuas muaj xya lub ntsiab lus cais:

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

Qhov thib ob, ua li cas koj thiaj paub yog tias lub ntsiab yog malleable? Yog mas , cov khoom yuav raug flattened rau hauv cov ntawv nyias los ntawm hammering los yog dov. Malleable cov ntaub ntawv tuaj yeem flattened rau hauv cov nplooj hlau. Ib qho zoo- paub hom nplooj hlau yog nplooj kub. Ntau cov hlau nrog siab kev ua tau zoo kuj muaj ductility siab.

Kuj tseem paub yog, dab tsi cais cov metalloid?

A metalloid yog ib qho tshuaj lom neeg uas nthuav tawm qee yam khoom ntawm cov hlau thiab qee cov nonmetals. Boron, silicon, germanium, arsenic, antimony, tellurium, thiab polonium yog metalloids . Qee qhov xwm txheej, cov kws sau ntawv kuj tseem tuaj yeem kawm selenium, astatine, aluminium, thiab carbon li metalloids , tab sis qhov no tsis tshua muaj.

Yuav ua li cas koj thiaj paub tias tej yam yog hlau los yog nonmetal?

Cov hlau yog nyob rau sab laug ntawm kab (tshwj tsis yog hydrogen, uas yog a nonmetal ), cov nonmetals yog nyob rau sab xis ntawm txoj kab, thiab cov khoom tam sim ntawd nyob ib sab ntawm txoj kab yog cov metalloids.
