Ntsiab Lus

  1. Lattice zog yog txhais raws li tus zog yuav tsum cais ib mole ntawm ib qho khoom ionic rau hauv gaseous ions.
  2. Lattice zog tsis tuaj yeem ntsuas qhov pom, tab sis nws tuaj yeem suav nrog siv electrostatics lossis kwv yees siv lub voj voog yug-Haber.

Ib yam li ntawd, tib neeg nug, dab tsi yog lattice zog mis?

Lattice Zog thiab lub zog ntawm IonicBond Kev kwv yees ntawm lub zog ntawm cov ntawv cog lus hauv ib qho ioniccompound tuaj yeem tau los ntawm kev ntsuas qhov lattice zog ntawm lub compound, uas yog zog muab tawm thaum oppositelycharged ions nyob rau hauv cov roj theem tuaj ua ke los tsim assolid.

Ib tug kuj yuav nug, yog Lattice Zog ib txwm tsis zoo? Lattice Zog . Lwm lub ntsiab txhais hais tias lattice zog yog tus txheej txheem thim rov qab, lub ntsiab lus nws yog tus zog tso tawm thaum gaseous ions khi los ua ib qho ionicsolid. Raws li implied nyob rau hauv lub ntsiab txhais, cov txheej txheem no yuav ib txwm yuav exothermic, thiab yog li tus nqi rau latticeenergy yuav yog tsis zoo.

Ib yam li ntawd, tib neeg nug, qhov tsis tu ncua k hauv lattice zog yog dab tsi?

Tus nqi ntawm cov tas k ' nyob ntawm qhov kev npaj tshwj xeeb ntawm ions hauv cov khoom daim kab xev thiab lawvvalence electron configurations. Sawv cev qhov tseem ceeb forcalculated lattice zog , uas muaj li ntawm 600 mus rau 10, 000 kJ / mol, tau teev nyob rau hauv Table 1.

Qhov twg muaj ntau dua lattice zog NaCl lossis MgCl2?

U( MgCl 2 ) = 2477; U( NaCl ) = 769 kJ mol^-1 Ntau dua lattice zog implies zoo stability lub ntsiab lus muaj zog bonds.
