Cov daim ntawv cog lus ntawm N2 yog 3.o Nitrogen molecule. Rau qhov Bond Order ntawm N2 - yog 2.5 uas yog Nitrogen ion. nb = Number of electrons in kev sib raug zoo molecular orbitals.
Ntawm no, daim duab molecular orbital rau n2 yog dab tsi?
Atomic nitrogen muaj 5 valence electrons thiab 4 valence orbitals (2s, 2px,,2 p iby,,ua 2pz). Nyob rau hauv lub Lewis qauv muaj ib tug triple daim ntawv cog lus ntawm cov nitrogen atoms thiab ib tug uas tsis yog-bonding khub ntawm electrons ntawm ib leeg. Qhov no yog raws li lub cev muaj zog ntawm N2.
Ib yam li ntawd, daim ntawv cog lus ntawm c2 yog dab tsi? Yog li hauv C2 ; Peb tuaj yeem pom ob lub Carbons Doubly bonded, yog li qhov Bond Order hauv C2 = 2.
Electron configuration ntawm n2 yog dab tsi?
Yog li ntawd N electron configuration yuav 1s22s ib22 ib p3.
Muaj pes tsawg lub orbitals nyob hauv n2?
N2 molecule muaj 14 electrons thiab 7 OCCUPIED Orbitals.

Dab tsi ntawm daim ntawv cog lus tuav cov atoms ua ke hauv polyatomic ions?
Covalent bonding yog hom kev sib cog lus uas tuav ua ke cov atoms hauv polyatomic ion. Nws yuav siv ob lub electrons los ua covalent daim ntawv cog lus, ib qho los ntawm txhua qhov sib txuas atom. Lewis dot structures yog ib txoj hauv kev los sawv cev li cas atoms tsim covalent bonds
