Noble gases yog nonreactive, nonmetallic ntsiab nyob rau hauv pawg 18 ntawm lub sij hawm. Raws li koj tuaj yeem pom hauv daim ntawv teev npe hauv qab no, cov roj ntsha tseem ceeb suav nrog helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), thiab radon (Rn). Tag nrho cov pa roj carbon monoxide tsis muaj xim thiab tsis muaj ntxhiab.
Qhov twg yog qhov tsis muaj tshuaj tiv thaiv feem ntau?
Noble gases yog qhov tsawg tshaj plaws ntawm txhua lub ntsiab lus. Qhov ntawd yog vim lawv muaj yim valence electrons, uas ua rau lawv lub zog sab nraud. Qhov no yog qhov ruaj khov tshaj plaws ntawm electrons, yog li noble gases tsis tshua hnov mob nrog lwm cov ntsiab lus thiab daim ntawv sib txuas.
Lub ntsiab lus twg yog cov hlau tsis muaj zog?
Noble Metals pom tau tias yog cov hlau ntshiab vim tias lawv tsis ua haujlwm thiab tsis ua ke nrog lwm cov ntsiab lus los tsim cov tebchaw. Vim tias lawv yog cov nonreactive, lawv tsis corrode yooj yim. Noble hlau muaj xws li tooj liab, palladium, nyiaj, platinum, thiab kub.
Koj paub li cas lub ntsiab lus twg yog qhov tsawg tshaj plaws reactive?
Lub reactivity ntawm ib lub caij tuaj yeem txiav txim siab los ntawm kev saib cov khoom siv hluav taws xob ntawm lub caij. Yam tsawg kawg nkaus reactive yog cov uas muaj tag nrho cov sab nraud valence plhaubpiv txwv li lawv muaj 8 electrons nyob rau hauv lub plhaub sab nraud yog li cov ntsiab lus xws li helium, neon, radon lossis cov khoom hloov pauv.
Yuav ua li cas yog non reactive non metals?
Lwm cov roj uas tsis yog hlau muaj xws li hydrogen, fluorine, chlorine, thiab tag nrho cov pab pawg kaum yim noble (los yog inert) gases. Helium yog cov tshuaj tsis muaj zog, yog li nws muaj txiaj ntsig zoo rau cov ntawv thov xws li balloons (saib daim duab 3) thiab lasers, qhov uas tsis yog-flammable yog qhov tseem ceeb heev.
