O2分子轨道排布是（2S)^2(2S*)^2(2Px）^2(2Py)^2(2Pz）^2(2Py*)^1(2Pz*)^1
带*的是反键轨道
从前到后轨道能量由低到高，因此，正二价的O2没有反键电子，键级是4，正一价的有一个反键电子，因此键级是3.5，O2的反键电子是3，负一价的有三个反键电子，键级是2.5，负二价的有四个反键电子，因此键级是2。所以稳定性越来越差！
希望对你有所帮助！
如果有什么疑问，请追问！
望采纳！
O2 2+ (14e) ： (σ1s)2 (σ*1s)2 (σ2s)2 (σ*2s)2 (π2py)2 (π2pz)2 (σ2px)2
O2 + (15e) ： (σ1s)2 (σ*1s)2 (σ2s)2 (σ*2s)2 (σ2px)2 (π2py)2 (π2pz)2 (π*2py)1
O2 (16e) ： (σ1s)2 (σ*1s)2 (σ2s)2 (σ*2s)2 (σ2px)2 (π2py)2 (π2pz)2 (π*2py)1 (π*2pz)1
O2 - (17e) ： (σ1s)2 (σ*1s)2 (σ2s)2 (σ*2s)2 (σ2px)2 (π2py)2 (π2pz)2 (π*2py)2 (π*2pz)1
O2 2- (18e) ： (σ1s)2 (σ*1s)2 (σ2s)2 (σ*2s)2 (σ2px)2 (π2py)2 (π2pz)2 (π*2py)2 (π*2pz)2
由以上可见，键级分别是：3；2.5；2；1.5；1，对应稳定性依次减小。
