Calcium. Dab tsi tsis yog - hlau yog nyob rau hauv tib groupas lead ? Cov pa roj carbon.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi nonmetal nyob rau hauv tib pab pawg neeg ua lead?

Pab pawg 14 ntawm lub sij hawm lub sij hawm yog coj los ntawm lub nonmetal carbon (C), yog li no pab pawg tseem hu ua thecarbon pab pawg . Carbon yog ua raws li silicon (Si) andgermanium (Ge) (Daim duab hauv qab), uas yog metalloids, thiab tom qab ntawd bytin (Sn) thiab coj ( Pb ), uas yog cov hlau.

Ib yam li ntawd, pawg twg yog cov hlau thiab nonmetals? Cov metalloids yog ib qho tshwj xeeb pab pawg ntawm cov khoom uas qhia cov khoom ntawm ob qho tib si hlau thiab nonmetals . Lawv 'realso hu ua semimetals vim hais tias ntawm cov khoom sib koom ntawm cov ntsiab lus raws txoj kab sib faib ntawm hlau thiab nonmetals . Cov ntsiab lus uas yuav raug faib ua metalloidsinclude: Boron_ (B)

Hais txog qhov no, cov pab pawg twg yog cov hlau hauv?

Lub sij hawm nyob rau sab laug cais cov ntsiab lus rau hauv peb pab pawg : cov hlau (ntsuab nyob rau hauv lub rooj), nonmetals (txiv kab ntxwv), thiab metalloids (xiav). Cov ntsiab lus feem ntau yog hlau.

Puas yog hlau lead?

Boron, silicon, germanium, arsenic, antimony, thiabtellurium feem ntau lees paub tias yog metalloids . Lwm cov ntsiab lus qee zaus muab faib ua metalloids . Cov khoom no muaj xws li hydrogen, beryllium, nitrogen, phosphorus, sulfur, zinc, gallium, tin, iodine, coj , bismuth, andradon.
