Noble Gases
Lawv yog helium , neon , argon , krypton, xenon, thiab radon. Lawv ib zaug hu ua inert gases vim lawv tau xav tias yog tag nrho inert - tsis tuaj yeem tsim cov khoom sib xyaw. Qhov no yog ib qho kev ntseeg tsim nyog vim tias cov pa roj muaj octet tiav, ua rau lawv ruaj khov thiab tsis zoo li nce lossis poob ib qho hluav taws xob.
Xav txog qhov no, vim li cas helium yog inert gas?
Nyob rau saum cov noble cov pa yog me me helium (Nws), nrog lub plhaub uas puv nrog tsuas yog ob lub electrons. Qhov tseeb tias lawv cov plhaub sab nraud yog tag nrho txhais tau hais tias lawv zoo siab heev thiab tsis tas yuav hnov mob nrog lwm cov ntsiab lus. Qhov tseeb, lawv tsis tshua sib xyaw nrog lwm cov ntsiab lus. Qhov uas tsis yog-reactivity yog vim li cas lawv hu inert.
Tsis tas li ntawd, puas yog Argon roj inert? Argon Nws muaj kwv yees li tib yam solubility hauv dej li oxygen thiab yog 2.5 npaug ntau soluble hauv dej tshaj nitrogen. Argon yog xim tsis muaj ntxhiab, tsis muaj ntxhiab, nonflammable thiab nontoxic li khoom, kua los yog gas . Argon yog tshuaj inert nyob rau hauv feem ntau tej yam kev mob thiab cov ntaub ntawv tsis muaj kev ruaj ntseg tebchaw nyob rau hauv chav tsev kub.
Hauv qhov no, helium txawv ntawm neon thiab argon li cas?
1 Teb. Helium muaj lub plhaub sab nrauv ntawm tsuas yog 2 electrons Neon thiab Argon muaj cov plhaub sab nraud ntawm 8 lub tshuab hluav taws xob tag nrho peb tau ntim cov plhaub sab nraud thiab tsis tshua muaj kev ruaj ntseg.
Dab tsi yog kev siv cov roj inert?
Siv ntawm Noble Gases Cov cov pa roj yog siv ua form inert Cov huab cua, feem ntau rau arc vuam, tiv thaiv cov qauv, thiab tiv thaiv cov tshuaj lom neeg. Cov ntsiab lus yog siv nyob rau hauv cov teeb, xws li neon teeb thiab krypton headlamps, thiab nyob rau hauv lasers.

Dab tsi yog helium neon thiab argon muaj sib xws?
Kev piav qhia: Lub plhaub sab nraud ntawm Pawg VIIIA lossis cov roj hluav taws xob zoo ua rau kuv cov tswv cuab ntawm tsev neeg no (xws li Helium, Neon thiab Argon) ruaj khov tshaj plaws ntawm txhua lub ntsiab lus. Cov peb lub ntsiab lus no muaj cov cuab yeej zoo sib xws, ib qho chaw ruaj khov sab nrauv electron plhaub
Vim li cas A thiab T thiab G thiab C ua khub hauv DNA ob lub helix?
Qhov no txhais tau hais tias txhua ntawm ob strandsindouble-stranded DNA ua raws li ib tug templatetoproduce ob strands tshiab. Replication relies oncomplementary basepairing, uas yog lub hauv paus ntsiab lus piav qhia los ntawmChargaff cov cai: adenine (A) ib txwm khi nrog thymine (T) thiab cytosine (C) ib txwm khi nrog guanine (G)
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Dab tsi yog neon argon thiab krypton muaj sib xws?
Noble gases yog cov tshuaj nyob rau hauv pawg 18 ntawm lub periodic table. Lawv yog cov ruaj khov tshaj plaws vim muaj ntau tshaj plaws ntawm valence electrons lawv lub plhaub sab nraud tuaj yeem tuav. Cov tshuaj no muaj helium, neon, argon, krypton, xenon, thiab radon
