Hauv daim ntawv qhia hnub saum toj no, dub squares qhia hais tias yog cov khoom khib nyiab nyob rau hauv chav tsev kub (kwv yees li 22ºC) *, cov nyob rau hauv xiav squares yog kua nyob rau hauv chav tsev kub, thiab cov nyob rau hauv liab squares yog gases nyob rau hauv chav tsev kub.
Tsuas yog li ntawd, cov xim ntawm lub sij hawm lub sij hawm txhais li cas?
Cov rooj zaum siv tau xim txhawm rau txheeb xyuas lwm yam yam ntxwv. Piv txwv li, electronegativity periodic rooj xim codes cov ntsiab lus raws li electronegative lawv li cas. Lub valence daim ntawv qhia hnub siv xim txhawm rau txheeb xyuas qhov feem ntau valence xeev rau txhua lub caij.
Dab tsi yog cov khib nyiab ntawm lub rooj zaum? Nyob rau hauv chav tsev kub feem ntau cov ntsiab lus yog khoom. Tsuas muaj ob lub kua mercury (Hg) thiab bromine (Br) thiab ib lub kaum los yog li ntawd gases. Tab sis yog tias koj nqes mus rau 4K tsuas muaj ib qho roj thiab lwm yam khoom muaj zog. Ntawm 5000K lossis yog li ntawd tsuas yog ib qho uas tsis yog roj tseem yog tungsten (W).
Kuj tseem yuav paub, cov xim ntawm cov ntsiab lus ntawm lub rooj zaum yog dab tsi?
Hauv nws patent nws hais txog cov xim hauv qab no:
- Dawb rau hydrogen.
- Dub rau carbon.
- Xiav rau nitrogen.
- Liab rau oxygen.
- Sib sib zog nqus daj rau sulfur.
- Ntshav rau phosphorus.
- Lub teeb, nruab nrab, nruab nrab tsaus, thiab tsaus ntsuab rau cov halogens (F, Cl, Br, I)
- Nyiaj rau hlau (Co, Fe, Ni, Cu)
Nws txhais li cas thaum ib qho khoom luam tawm hauv cov xim dub ntawm lub rooj zaum?
Dub = Khoom hauv chav temp.

Dab tsi yog lub ntsiab lus 11 ntawm lub rooj zaum?
Sodium yog lub ntsiab lus uas yog atomic naj npawb 11 ntawm lub sijhawm teem sijhawm
Dab tsi yog thawj lub ntsiab lus ntawm lub rooj zaum?
Hydrogen yog thawj lub hauv paus ntawm lub rooj sib tham, nrog qhov nruab nrab atomic loj ntawm 1.00794
Lub suab nrawm npaum li cas los ntawm cov khib nyiab?
Lub suab tuaj yeem taug kev ntawm kwv yees li 6000 metresper thib ob hauv qee cov khib nyiab thiab ntawm ib feem peb ntawm qhov ceev hauv dej. Qhov no yog vim hais tias cov molecules ntawm cov khib nyiab tau ntim ntau dua ua ke dua li hauv cov kua thiab cov dej hauv cov kua yog ntim nruj dua li cov pa roj
Dab tsi yog cov khoom siv hluav taws xob ntau tshaj plaws ntawm lub rooj zaum?
Polonium Tsis tas li ntawd, nyob qhov twg yog cov xov tooj cua tshaj plaws nyob rau hauv lub sijhawm? Actinide Series ntawm Hlau Muaj ob kab hauv qab daim ntawv qhia hnub : lanthanide thiab actinide series. Lub lanthanide series tuaj yeem pom nyob rau hauv lub ntiaj teb.
Cov khib nyiab khib nyiab yog dab tsi?
Cov khib nyiab pov tseg txhais tau hais tias cov khib nyiab uas tshwm sim los ntawm kev ua haujlwm hauv av. Cov khib nyiab pov tseg txhais tau tias cov khoom pov tseg uas tshwm sim los ntawm kev ua haujlwm tshem tawm av. Cov khib nyiab pov tseg muaj xws li stumps, ntoo, txhuam, nplooj, av, thiab txoj kev spoils
