An ion is a particle that has a net electrical charge. An ion with a positive charge is called a proton and an ion with a negative charge is called an anion. When a stable atom gains or loses electrons then it is called an ion. ...
termed "ligands". A dative bond is a type of covalent bond, in which the ligand donates both of the valence electrons required. A single ligand can have two or more different donor groups that bind to the metal cation. Such a ligand is termed...

The liquid polyatomic ion beam generators whichPROBLEM TO BE SOLVED: To develop surface reforming, and appreciably stable surface reforming, by controlling chemical properties such as a hydrophilic property and a hydrophobic property, and an addition/substitution reaction.高岡 義寛...
The ammonium cation is a positively charged polyatomic ion with the chemical formula NH^(+4). It is formed by the protonation of ammonia.
Draw the Lewis dot structure for the polyatomic ion, carbonate (CO_3^{2-}). Do not forget to draw all lone pairs. Write Lewis formulas for six different resonance forms of the sulfate ion, SO_4^(2-). Indicate all formal charges. Predict which ...
Insight into the Molecular Mechanism by which a Green Tea Extract inhibits hIAPP Aggregation Yuxiang Mo1,2, Jiangtao Lei1,Yunxiang Sun1, Qingwen Zhang3 & Guanghong Wei1 Small oligomers formed early along human islet amyloid polypeptide (hIAPP) aggregation is responsible for the cell ...
Small oligomers formed early along human islet amyloid polypeptide (hIAPP) aggregation is responsible for the cell death in Type II diabetes. The epigallocatechin gallate (EGCG), a green tea extract, was found to inhibit hIAPP fibrillation. However, the
when R1 is an alkylene group, R3 and R4 are polyatomic groups, and when G1 is a substituent defined for Nu, an adjacent R3 or R4 can be the group: ##EQU6## X1 is a ballasting group of sufficient size to render said compound immobile in an alkali-permeable layer of the photographic...
