若问题涉及化学领域,键级(Bond Order)表示原子间化学键的数量和强度,例如: 计算方法:键级=(成键电子数-反键电子数)/2; 常见示例:氧气(O₂)键级为2,氮气(N₂)键级为3; 意义:键级越高,化学键越稳定,键长越短。 3. 建议核实问题准确性 由于“b2键级”未被广泛定义,建议确认以下内...

The stable configuration of energy, structure, bond and charge are analyzed. Results show that the cluster Sc3B2 can exist stably in configuration of trigonal bipyramid, mono capped trigonal pyramidal and quadrangular pyramid, only one plane pentagonal. The best stability structure is 1(2) in all...
