Muaj roj av

Gases tsis tshua muaj pa, kuj tseem hu ua gases thiab cov roj uas muaj txiaj ntsig, yog ib pawg ntawm cov ntsiab lus uas pom muaj nyob hauv cov pa roj ntau hauv cov huab cua thiab yog ruaj khov. Rare gases are located in Group Zero of the Periodic Table and include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), which has only recently been added to the Periodic Table family of elements.
Cov roj av tsis tshua muaj siab rau txog 0.94% ntawm cov ntsiab lus cua, feem ntau yog tsis muaj zog, Krypton, tsis muaj peev xwm siv tau los ua cov pa roj av thiab lub siab, tuaj yeem siv los ua cov pa roj teeb Monatomic teb.
Nrog rau kev zam ntawm cov lus German, uas tsuas yog tuaj yeem tau synthetically, yog qhov tsis ruaj khov thiab tsis ruaj khov, lwm yam tsawg kawg ntawm cov ntawv thov hauv ntau yam uas tsis yog kev tiv thaiv roj. Atomic Mass tsuas yog siab dua hydrogen, qhov xwm ntawm cov roj uas muaj pa hluav taws xob nrog kev zais pa hluav taws xob nrog cov pa zais pa roj carbon monoxide Argon los ntawm lub siab-zog Cosmic Rays yuav muaj ionized tom qab kev tawm dag zog, tuaj yeem tsim tsa qhov chaw ntawm Cosmic Roadiation thiab kev siv ntawm cov cosmic chaw; Xenon yuav yaj nyob rau hauv cov lipidular cellids, ua rau cov tshuaj loog ntawm cev. Xenon tuaj yeem yaj nyob rau hauv cov lipids ntawm lub hlwb, ua rau tuag tes tuag taw thiab o ntawm lub hlwb, thiab ua rau cov hlab hlwb nres ua haujlwm ib ntus. Nws tuaj yeem sib xyaw nrog oxygen ntawm ib feem ntawm 4: 1 ua tshuaj loog tsis muaj kev phiv; Radon, raws li cov roj hluav taws xob nkaus xwb hauv qhov xwm, tuaj yeem tsim los ntawm cov ntaub ntawv tsis zoo, tab sis nws tuaj yeem sib xyaw nrog cov hmoov av tsis zoo thiab siv los ua nruab nrab hauv chaw soj ntsuam.
Rare Gases emit ci thiab tshee tshee thaum energized. Los ntawm txhaws teeb cov kev sib xyaw ntawm ntau hom thiab proportions ntawm belium, cov lus sib dhos, thiab cov lus sib txawv, thiab cov khoom lag luam zoo nkauj tuaj yeem tau txais ntau yam xim.
Lub ntsiab lus melting thiab boiling taw tes ntawm cov roj tsis tshua muaj roj tsawg, thiab cov kev ua kom muaj cua txias thiab tom qab ntawd, Argon, Krypton thiab Xenon; Helium feem ntau yog muab rho tawm los ntawm cov nkev; Thiab radon feem ntau tau sib cais los ntawm radium sib txuas tom qab nruab nrab lwj.
Shanghai Jiuzhou Zeolite molecular sab cib, tsis tshua muaj roj sib cais, siab nrawm, raws li kev ua haujlwm sib txawv, raws li kev ua haujlwm sib txawv los muab koj cov kev pabcuam sib txawv. Peb cia siab tias yuav koom tes nrog koj los tsim lub neej tom ntej zoo dua.
