A cation is smaller in size than its corresponding atom and an anion is larger than its corresponding atom. Answer and Explanation: Part (a) {eq}\mathbf{Li^+} \ \text{and} \ \mathbf{Li} {/eq} The cation is smaller ...
To identify: The species which will have smaller size. In the given set of anions which will be larger has to be identified and explained. Concept Introduction: The distance between the nucleus and the valence shell of a cation or an anion is known ...
Why Mg^{2+} ion has smaller radius than Mg atom? Why is the Na+ ion is smaller than a neutral Na atom? Why and how does the atomic radius change when an atom becomes a cation or an anion? (a) Element to cation. (b) Element to anion. ...
A number of students are able to explain that the thermal decomposition of Group 1 nitrate is related to polarisation of nitrate anion by Li* cation. However, most of them failed to compare it with that of Group 1cations. Most students failed to provide the explanation that it due to ...
4b, the hydrated cation has a much more detrimental effect, as shown in Fig. 4c. The minor role played by Cl− is consistent with its flexible FSS structure, in which 28% of water molecules are not hydrogen-bonded by the Cl− anion. These nonbonded FSS water molecules are likely to...
In this respect, it is perhaps noteworthy that the replacement of Tyr166 by a less bulky amino acid in an unrelated GH43 arabinoxylan hydrolase (AXHd3 from Humicola insolens) also provoked a significant modifi- cation of active topology and facilitated the productive binding of xylo-oliogo...
An electrochemical device and a proton conducting medium for use in an electrochemical device having a proton conducting electrolyte comprising the formula: H a M b Q.nH 2 O where H is a proton, M is a cation, Q is the fluoroborate or fluoroheteroborate anion, n ranges from 0.01 to ...
For the normal human eye in vivo, Quintyn and Brasseur estimate a flow rate through the RPE to be about 2.5 ± 1.25 μl/min (Quintyn and Brasseur, 2004). This estimate is somewhat smaller than the mean estimate of 3.0 μl/min made using an independent method reported by Smith and ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
specific surface area, cation exchange capacity, elemental composition, etc. A standardized method of determination should be developed to record accurate values and allow relevant comparisons between compounds. Before all, a clear definition of "EDC" itself should be dis- cussed. Should the choice ...
