a species that contains a lone pair of electrons that forms a dative bond to a metal atom/ion. Transition element: (an element) forming (one or more stable) ions with incomplete d subshell. 当然,看完了这些,还需要巩固下别的知识点,不能放假了心就飞了,因为再飞回来就比较难了。 温故而知新...
Establishing a Transition Period to Foster a Long-term Anti- poverty Mechanism Even after shaking off poverty, some farmers are still at risk of slipping back into poverty. To cope with this, China has carried out county-level monitoring, relying on households and rural cadre inspections to ...
Topological design of π electrons in zigzag-edged graphene nanoribbons (ZGNRs) leads to a wealth of magnetic quantum phenomena and exotic quantum phases1,2,3,4,5,6,7,8,9,10. Symmetric ZGNRs typically show antiferromagnetically coupled spin-ordered edge states1,2. Eliminating cross-edge magnet...
In July 2012, the ATLAS and CMS collaborations at the CERN Large Hadron Collider announced the observation of a Higgs boson at a mass of around 125 gigaelectronvolts. Ten years later, and with the data corresponding to the production of a 30-times larger number of Higgs bosons, we have...
