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:
- Boron.
- Silicon.
- Germanium.
- Arsenic.
- Antimony.
- Tellurium.
- 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.

Yuav ua li cas koj qhia yog hais tias ib tug transformation yog ib tug dilation?
Ib qho kev piav qhia ntawm qhov dilation suav nrog qhov ntsuas qhov ntsuas (lossis qhov piv) thiab qhov nruab nrab ntawm qhov dilation. Qhov chaw ntawm dilation yog ib qho chaw ruaj khov hauv lub dav hlau. Yog tias qhov ntsuas qhov ntsuas ntau dua 1, daim duab yog qhov loj (qhov ncab). Yog tias qhov ntsuas qhov ntsuas nyob nruab nrab ntawm 0 thiab 1, daim duab yog qhov txo qis (qhov qis)
Yuav ua li cas koj qhia yog hais tias ib tug khub ntawm ratios tsim ib tug proportions?
Sim xav seb puas yog ob qho piv txwv yog proportional? Yog tias lawv nyob hauv daim ntawv feem, muab lawv sib npaug rau ib leeg los kuaj seb lawv puas yog proportional. Hla multiply thiab simplify. Yog tias koj tau txais cov lus tseeb, ces qhov sib piv yog proportional
Yuav ua li cas koj thiaj paub yog hais tias ib tug function tsis yog ib tug function?
Kev txiav txim siab seb qhov kev sib raug zoo yog qhov ua haujlwm ntawm daim duab yog qhov yooj yim los ntawm kev siv cov kab ntsug. Yog tias txoj kab ntsug hla qhov kev sib raug zoo ntawm daim duab ib zaug hauv txhua qhov chaw, qhov kev sib raug zoo yog qhov ua haujlwm. Txawm li cas los xij, yog tias txoj kab ntsug hla qhov kev sib raug ntau dua ib zaug, qhov kev sib raug zoo tsis muaj nuj nqi
Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
Yuav ua li cas koj qhia yog hais tias ib tug piecewise graph yog ib tug muaj nuj nqi?
Yuav Qhia Li Cas Yog Piecewise Function yog Nruam lossis Tsis Txuas Ntxiv. Txhawm rau qhia yog tias daim duab sib txuas tsis tu ncua lossis tsis txuas ntxiv, koj tuaj yeem saib cov ntsiab lus ciam teb thiab pom tias y point yog tib yam ntawm lawv txhua tus.(Yog tias y's txawv, yuav muaj "dhia" hauv daim duab !)
