Neon vs Lead
Cov ntsiab lus hauv lub rooj zaum muaj qhov sib txawv. Peb tuaj yeem categorize lawv raws li lawv tus lej atomic thiab tuaj yeem pab pawg sib xws. Neon thiab lead ob yog p thaiv cov ntsiab lus, vim tias lawv cov electron kawg tau ntim rau p orbital.
Neon Neon Nyob
Neon yog lub thib kaum nyob rau hauv lub sij hawm, thiab nws yog nyob rau hauv pawg 18 (Nobel gas). Nws muaj kaum electrons; Yog li ntawd, lub configuration electron yog 1s2 2s2 2p6 p orbital tsuas tuaj yeem haum rau 6 electrons, Yog li nyob rau hauv helium p orbital yog puv puv ua neon ib qho inert roj. Ne yog lub cim ntawm Neon, thiab nws qhov hnyav atomic yog 20.17 g mol-1 Neon yog ib qho inert, tsis muaj xim, roj raws li tus qauv. Nws yog ib qho roj av ntau heev hauv ntiaj teb, tab sis nws tsis tshua muaj nyob hauv ntiaj teb. Nws kuj muaj qhov kub tsis tshua muaj kub, qhov ntom ntom. Neon yog lub teeb roj (qhov thib ob lightest inert gas), thiab nws tsis yog tshuaj lom. Neon muaj peb lub isotopes ruaj khov, ntawm cov 20 Ne yog cov isotope tshaj plaws. Txij li thaum neon yog cov roj ruaj khov, nws tsis muaj kev cuam tshuam thiab tsis tsim ntau lub tebchaw. Txawm li cas los xij, nws cov hom ionic zoo li (NeAr)+ thiab (NeH)+ tau pom. Yog li ntawd, peb tuaj yeem hais tias txhua qhov nruab nrab ntawm neon tseem tsis tau pom dua. Neon muaj cov yam ntxwv tshwj xeeb vim nws ci xim liab liab hauv lub tshuab nqus tsev vacuum. Yog li ntawd, neon yog siv nyob rau hauv neon teeb, cov paib, TV tubes, helium-neon lasers, thiab lwm yam.
Nyob
Lead muaj lub cim Pb, vim nws lub npe Latin Plumbum. Qhov no yog nyob rau hauv lub p block ntawm lub periodic rooj. Nws yog nyob rau hauv pawg carbon thiab muaj atomic tooj ntawm 82. Electron configuration of lead is [Xe] 4f145d10 6s2 6p 2 Txij li thaum nws muaj plaub lub electrons hauv lub plhaub valence, nws tuaj yeem tsim +4 oxidation xeev. Nws kuj qhia tau hais tias +2 oxidation xeev. PbO thiab PbO2 yog cov oxides tsim los ntawm cov hlau lead hauv ntau lub xeev oxidation. Cov hmoov txhuas muaj cov xim zoo nkauj thaum nws tau txiav tshiab. Txij li thaum nws yog heev reactive nrog oxygen nyob rau hauv cov huab cua, lub ci yuav ploj mus raws li cov hlau lead ua oxides. Lead yog lub npe hu ua hnyav hlau. Nws yog mos heev, heev malleable, thiab ductile. Txawm hais tias nws yog hlau, nws muaj hluav taws xob tsis zoo. Lead hmoov kub hnyiab nrog ib tug yam ntxwv bluish dawb nplaim taws. Thiab cov tshuaj lom fumed raug tso tawm thaum nws hlawv. Lead muaj ntau cov isotopes. Feem ntau ntawm lawv yog tsim los ntawm radioactive decay ntawm cov ntsiab lus hnyav. Plaub isotopes ntawm txhuas yog 204 Pb, 206 Pb, 207 Pb, thiab 208Pb. Los ntawm cov no, 206Pb, 207Pb, thiab 208Pb ruaj khov. Cov hmoov txhuas muaj nyob rau hauv qhov sib xyaw nrog lwm cov ntsiab lus xws li sulfur, Zn, Cu thiab lwm yam. Cov hlau lead ntshiab tsis tshua pom muaj nyob hauv qhov xwm txheej. Galena (PbS) yog cov hlau lead tseem ceeb nrog cov feem pua ntawm cov hlau lead ntau dua hauv nws. Lead yog corrosive resistant; yog li ntawd, nws yog siv rau hauv kev tsim vaj tsev. Tsis tas li ntawd nws yog siv nyob rau hauv cov roj teeb lead-acid, mos txwv, thiab raws li hluav taws xob tiv thaiv. Lead paub tias yog ib qho tshuaj lom. Thaum nws khaws cia rau hauv cov kab mob lom, nws tuaj yeem ua rau cov kab mob neurological, ntshav thiab hlwb. Lawv tuaj yeem nkag mus rau hauv peb lub cev los ntawm zaub mov thiab dej.
Qhov txawv ntawm Neon thiab Lead yog dab tsi?
• Neon yog roj, thiab txhuas yog cov khoom.
• Txij li thaum neon yog cov roj thiab txhuas yog cov khoom, lawv lub cev thiab tshuaj lom neeg muaj zog sib txawv ntawm ib leeg. -
• Neon yog inert, tab sis lead yog heev reactive.
• Lead forms compounds with +2 and +4 oxidation states, whereas neon tsis tsim cov tebchaw xws li.
• Lead yog lom rau tsiaj thaum nws sau.
