Ma’ruza kimyoviy bog’lanish va ularning turlari

18- rasm. Kislorod molekulasi hosil bo‘lishining energetik sxemasi.
Kimyoviy bog‘ hosil bo‘lishida faqat 2- pog‘ona elekt­ronlari qatnashayotganligini e’tiborga olib hamda bo‘shashtiruvchi orbitalni yulduzcha bilan belgilab, molekulaning elektron formulasini ixchamroq ko‘rishinda yozish mumkin:
O₂ [KK ( _s) ² ( ^∙_s) ² ( _px) ^{2 (} _py) ² ( _pz) ² ( ^∙_py) ¹ ( ^∙_pz) ¹].
