Aluminum is a main-group metal and therefore loses electrons to form a cation with the same number of electrons as the nearest noble gas. Are cation atoms that have lost an electron positively charged What is the difference between ionic bonding and a redox reaction?
Adsorption of cadmium and sulfate in a mixed Fe(OH)3SiO2 system was studied using the triple-layer model. The uptake of H 4 SiO 4 dissolved from the SiO 2 particles was considered in modeling the cation and anion adsorption. The mixed oxides were formed with a range of Fe(OH) 3 :SiO...
一般来讲,金属与非金属之间形成ionic bond。其内在逻辑的简化版是金属元素在周期表中占据左下角,原子半径比较大,原子核与最外层电子距离较远,易失电子形成阳离子(cation)。非金属元素在周期表中占据周期表右上角,原子半径比较小,原子核与最...

Spin-Singlet Transition in the Magnetic Hybrid Compound from a Spin-Crossover Fe(III) Cation and π-Radical Anion To develop a new spin-crossover functional material, a magnetic hybrid compound [Fe(qsal)2][Ni(mnt)2] was designed and synthesized (Hqsal = N-(8-quinolyl)salicylaldimine, mn...
In both sets of structures, the cations appear to perform a templating function and lie in pairs within cavities in the anionic network. These cation pairs show pseudo-6-fold phenyl embraces. No long-range magnetic ordering intrinsic to these materials was observed, although traces of the ...
The variation of the valence states of structural iron in clay minerals tends to affect many different aspects of their physicochemical properties (e. g., surface area, water swellability and cation and anion exchange capacity, etc.), which can further influence nutrient cycling, plant growth and...
The existence of Fe2NiO4 in the nano-network changes the ion-exchanging properties of rust from anion to cation selective. Then, the rust on the advanced weathering steel "breathes out" chloride ions from the rust/steel interface, and protects steel for more than a century by reducing the ...

The cation/vacancy distribution forms a homogeneous 3D arrangement and could represent the absolute cationic ordering available in the full Na3M2(PO4)3 series, as verified for M = Fe. For M = Ti, the reversible α→γ transition was observed at 85 °C, leading to the standard disordered ...
