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.
