Boron, silicon, germanium, arsenic, antimony, thiab tellurium feem ntau lees paub tias yog metalloids . Lwm cov ntsiab lus qee zaus muab cais ua metalloids . Cov khoom no muaj xws li hydrogen, beryllium , nitrogen, phosphorus, sulfur, zinc, gallium, tin, iodine, lead, bismuth, thiab radon.
Kuj paub, yog beryllium yog hlau lossis metalloid?
Vim li cas thiaj suav tias yog li ntawd? Beryllium yog a hlau . Nws yog nyob rau hauv lub ntiaj teb alkaline hlau pab pawg inn lub sij hawm thiab muaj tshuaj lom neeg thiab lub cev muaj zog zoo ib yam li cov magnesium thiab txhuas, tab sis muaj qhov sib txawv ntau dua melting point dua li.
Tsis tas li ntawd, 8 metalloids yog dab tsi? Cov yim cov ntsiab lus cais raws li metalloids yog boron, silicon, germanium, arsenic, antimony, tellurium, astatine, thiab polonium. Metalloids tshwm sim raws kab pheeb ces kaum-kauj ruam ntawm cov hlau thiab cov hlau tsis yog hlau.
Ib yam li ntawd, tib neeg nug, tsev neeg twg yog beryllium?
Beryllium yog lub lightest tswv cuab ntawm alkaline ntiaj teb hlau tsev neeg . Cov hlau no ua rau Pawg 2 (IIA) ntawm lub rooj sib tham. Lawv suav nrog beryllium , magnesium, calcium, strontium, barium, thiab radium. Cov ntsiab lus nyob rau hauv tib kem ntawm lub sij hawm lub sij hawm muaj cov tshuaj zoo sib xws.
Puas yog arsenic yog metalloid?
Arsenic yog ib qho tshuaj lom neeg nrog lub cim As thiab tus lej atomic 33. Arsenic tshwm sim nyob rau hauv ntau yam minerals, feem ntau nyob rau hauv ua ke nrog sulfur thiab hlau, tab sis kuj raws li ib tug ntshiab elemental siv lead ua. Arsenic yog a metalloid.
