A cation refers to an atom or a group of atoms that bear one or multiple positive electric charges. An anion refers to an atom or a group of atoms that bear one or multiple negative electric charges.

Dot and cross diagrams help us to model when ions are formed from atoms. Here’s an example using sodium and chlorine. They form ions which bond to form sodium chloride. 2. Work out how many ...

The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit cell with ion locations indicated (a) and a space filling model (b ...

POSTECH, Korea Research Institute of Chemical Technology, and Chonnam National University develop innovative ionic liquid ...

and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc structure and the zinc ions occupy half of the tetrahedral sites in this structure to attain charge ...

A group of researchers from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has designed and ...

The rules can be bent when ions get together. When light is passed through a compound or mineral containing a transition metal ion, it is found that certain wavelengths are absorbed, often leading to ...

The scheme is driven by moderate heat — temperatures less than 100° C — generated directly from sunlight, or waste heat from ...

We sell different types of products and services to both investment professionals and individual investors. These products and services are usually sold through license agreements or subscriptions ...

Ionic liquids are salts that remain in a liquid state at room temperature or even at relatively low temperatures due to strong electrical interactions between their ions. Unlike common salts ...

South Korean researchers have designed a power pack that reliably provides energy using salt and air, both abundant or free ...
