Cov pa roj carbon muaj 4 electrons nyob rau hauv nws valence plhaub uas ua rau nws ib tug metalloid tab sis feem ntau nws suav hais tias yog asa tsis yog hlau.
Ib yam li ib tug yuav nug, puas yog carbon hlau lossis metalloid?
Cov pa roj carbon yog a nonmetal , thiab cov ntsiab lus tseem ceeb hauv pab pawg no yog hlau . Pab pawg 15 yog hu ua pawg nitrogen. Cov metalloids nyob rau hauv pawg no yog arsenic andantimony.
Tsis tas li ntawd, vim li cas carbon tsis yog metalloid? Cov pa roj carbon tsis muaj lub cev ntawm cov hlau. Feem ntau cov hlau feem ntau yog lustrous, opaque, khoom, thiab qee qhov yog malleable thiab ductile. Cov hlau kuj yog cov conductors zoo heev.
Ib yam li ntawd, nws raug nug, puas yog carbon suav tias yog hlau lossis nonmetal?
Cov pa roj carbon (los ntawm Latin: carbo "coal") yog chemicalelement nrog lub cim C thiab atomic tooj 6. nonmetallic thiab tetravalent-ua plaub electronsavailable los tsim covalent tshuaj bonds. Nws belongs rau pawg 14 ntawm lub sijhawm teem sijhawm.
Puas yog mg yog hlau nonmetal lossis metalloid?
Cov tub ntxhais kawm pawg tau faib magnesium , zinc , hlau thiab tin li hlau ; sulfur ua nonmetal thiab silicon thiab carbon li metalloids . Carbonconducts hluav taws xob thiab tsis muaj cov yam ntxwv zoo.

Beryllium yog hlau. Nws yog nyob rau hauv alkaline ntiaj teb hlau pawg nyob rau hauv lub periodic lub rooj thiab muaj tshuaj thiab lub cev muaj zog zoo ib yam li cov magnesium thiab txhuas, tab sis muaj ib tug ntau dua melting point tshaj ob qho tib si
Puas yog Lithium yog hlau lossis nonmetal?
Lithium yog ib feem ntawm pawg hlau alkali thiab tuaj yeem pom nyob rau hauv thawj kem ntawm lub rooj zaum hauv qab hydrogen. Zoo li tag nrho cov alkali hlau nws muaj ib qho hluav taws xob valence uas nws yooj yim muab los ua ib qho cation lossis compound. Nyob rau hauv chav tsev kub lithium yog ib tug mos hlau uas yog silvery-dawb nyob rau hauv cov xim
Puas yog malleable hlau lossis nonmetal lossis metalloid?
Hlau, Metalloids, thiab Nonmetals. Cov ntsiab lus tuaj yeem faib ua hlau, nonmetals, lossis metalloids. Cov hlau yog cov khoom siv hluav taws xob zoo ntawm cov cua sov thiab hluav taws xob, thiab tuaj yeem ua tau zoo (lawv tuaj yeem muab hammered rau hauv cov ntawv) thiab ductile (lawv tuaj yeem kos rau hauv cov hlau). Cov metalloids yog nruab nrab hauv lawv cov khoom
Puas yog bromine yog hlau nonmetal lossis metalloid?
Bromine yog qhov thib peb halogen, yog ib qho nonmetal nyob rau hauv pawg 17 ntawm lub sij hawm. Nws cov khoom yog li zoo ib yam li cov fluorine, chlorine, thiab iodine, thiab zoo li nruab nrab ntawm cov neeg nyob sib ze ntawm halogens, chlorine thiab iodine
