Sulfur yog ib qho tshuaj keeb uas yog sawv cev nrog cov cim tshuaj "S" thiab tus lej atomic 16 ntawm lub rooj sib tham . Selenium yog cov hlau tsis muaj hlau thiab tuaj yeem muab piv rau tshuaj lom neeg rau nws cov khoom tsis yog hlau pom hauv Pab Pawg. 16 : Tsev Neeg Oxygen, xws li sulfur thiab tellurium.
Ua li no, dab tsi yog chalcogen ntsiab?
d??nz/) yog cov tshuaj cov ntsiab lus nyob rau hauv pawg 16 ntawm lub sij hawm. Cov pab pawg no tseem hu ua tsev neeg oxygen. Nws muaj cov cov ntsiab lus oxygen (O), sulfur (S), selenium (Se), tellurium (Te), thiab cov xov tooj cua keeb polonium (Po).
Ib tug kuj tseem nug, yog Pawg 16 ntawm lub rooj sib tham ua haujlwm tsis zoo? Pawg 16 ntawm daim ntawv qhia hnub kuj hu ua oxygen pab pawg . Thawj peb lub ntsiab - Oxygen (O), sulfur (S), thiab selenium (Se) - yog nonmetals. Lawv ua raws li tellurium (Te) (Daim duab hauv qab), ib qho metalloid, thiab polonium (Po), hlau. Tag nrho pab 16 cov ntsiab lus muaj rau valence electrons thiab yog heev reactive.
Ib yam li ntawd, koj tuaj yeem nug, vim li cas 16 pab pawg hu ua Chalkogens?
Cov chalcogens yog lub npe rau lub Rooj Sib Tham pab 16 (los yog V1). Cov pab pawg muaj cov cov ntsiab lus : oxygen, sulfur, selenium, tellurium, thiab polonium. Lub sij hawm " chalcogens " tau muab los ntawm Greek lo lus chalcos, lub ntsiab lus "ore qub," vim lawv txhua tus muaj nyob rau hauv tooj liab ores.
Dab tsi yog tag nrho cov ntsiab lus ntawm lub rooj zaum?
Cov ntsiab lus ntawm lub rooj sib tham tau txheeb los ntawm tus lej atomic
Atomic naj npawb | Lub npe tshuaj lom neeg | Cim |
---|---|---|
6 | Cov pa roj carbon | C |
7 | Nitrogen | N |
8 | Oxygen | O |
9 | Fluorine | F |
