, a proposed extension of the idea of aromaticity to particularly stable non-cyclic structures. this concept was proposed originally to explain the uncommon stability of the guanidinium cation. you can find some references in the wikipedia article on aromaticity under "atypical aromatic ...
Magnesium Ions have a stable electronic configuration. The stability of Magnesium ions makes them less reactive than the atoms. 8 Magnesium Atom A Magnesium Atom can react and form compounds by losing electrons. Magnesium atoms react with oxygen to form Magnesium oxide. 5 Magnesium Ion It is posi...
But I recommend saving up and waiting until you’ve got the budget to go on a proper Antarctic cruise where you get to land on the continent, swim in the icy waters and have penguins waddling just a few feet away from you. It makes a whole of a difference! Last Minute Antarctica Crui...
An essential protein of the SARS-CoV-2 virus, theenvelope protein E, forms a homopentameric cation channel that is important for virus pathogenicity. What is the N protein in Covid 19? TheNucleocapsid Protein(N Protein) of severe acute respiratory syndrome Coronavirus 2 (SARS-CoV2) is locate...
The formation of superficial complexes would act as an enhancer to allow interaction with hydrous oxides (which interfere on cation-exchange) and metal/metalloid ions. Such hydrogenous-biogenic coatings occur through formation of metallic oxides on the surface of polymers which promote co-precipitation...
What is a free radical? Atom: The smallest part of a living or non-living thing consists of a central nucleus surrounded by one or more electrons is called an atom. The number of protons present in the nucleus of an atom is designated as an atomic number of an element and it is ...

Tungsten is mainly a hexavalent cation in nature, and its ionic radius is 0.68×10-10m. Because W6+ has a small ion radius, high electricity price, strong polarization ability, and is easy to form complex anions, tungsten is mainly in the form of complex anions [WO4]2-, which combines ...
I have received countless reviews for papers submitted to journals that ask for some indi- cation of the frequency that underlies the presentation of a theme or category. Usually the question is something like, "Wouldn't it be useful information to know how many people were thinking in this ...
