Aoxygen is more electronegative Baddition of electron in oxygen results in larger size of the ion. Celectron repulsion outweiths the stability gained by achieving noble gas configuration. DO− ion has comparat
COxygen is more electronegative DO− ion has comparatively larger size than oxygen atomSubmit The formation of the oxide ion O2−g requires first an exothermic and then an endothermic step as shown below: Og+e−=O−g,ΔH∘=−142kJmol−1 O−g+e−=O2−g,ΔH∘=844k...
aThe oxygen atom of the water molecule is more electronegative than the hydrogen atom (i.e., it attracts more the electrons). As a result, the side of the molecule with the oxygen atom has a partial negative charge. A molecule with such a charge difference is called a dipole.[translate]...
29. A method of preparing the electrolyte of claim 1 comprising combining an alkali metal salt; a polar aprotic solvent; and redox shuttle additive that is an aromatic compound having at least one aromatic ring with four or more electronegative substituents, two or more oxygen atoms bonded to ...
(Chang2012, 19–20) according to their different aims and questions. For instance, aside from common interests, the phlogistonist and oxygenist systems also had diverging research questions that the other ‘competing’ system could not address (20–21). This is one of the causes that justifies...
Which is most electronegative element among the following? A. sodium B. bromine C. fluorine D. oxygen The more reactive an atom, the higher its potential energy. Which atom has higher potential energy, neon or fluorine? Which of the following is the strongest oxidizing agent? A. Fe3+(aq)...
When table salt is placed in water, the slightly electropositive sodium portion is attracted to the slightly electronegative oxygen portion of water molecules. At the same time, the slightly electronegative chlorine portion of NaCl is attracted to the slightly electropositive hydrogen portion of water...
oxygen The most electronegative element among the following is: A. sodium B. bromine C. fluorine D. oxygen If the electronegativity difference between the elements in compound NaX is 2.1, what is element X ? A. bromine B. chlorine C. fluorine D. oxygen Which of the following elements has ...
A Lewis acid catalystis generally used to initiate the cationic polymerization reaction by activation of the oxetane ring oxygen, allowing nucleophilic attack from the ring oxygen atom of a second oxetane molecule and ring opening. What is cationic vinyl polymerization?
the lack of van der Waals forces at the PTFE surface - is usually attributed to the very strong C-F single bond, and the extremely low polarizeability of fluorine. Fluorine is so electronegative that it holds its electrons very close to the nucleus, which lowers the probability that some ot...
