Li has the highest reducing power. why
NettetReducing agent: One of the reactants in an oxidation-reduction process is a reducing agent. It decreases the other reactant by releasing or donating electrons. Lithium: Lithium is represented by Li and has an atomic number 3. Because Lithium ions have higher hydration energy and a tendency to lose electrons, they are considered a powerful ... NettetWhy are potassium and caesium, rather than lithium used in photoelectric cells? Answer: Potassium and caesium have much lower ionization enthalpy than that of lithium. As a result, these metals easily emit electrons on exposure to light. Due to this, K and Cs are used in photoelectric cells rather than lithium. Question 10.

The cost of the rechargeable lithium-ion batteries used for phones, laptops, and cars has fallen dramatically over the last three decades, and has been a major driver of the rapid … NettetLithium has the highest negative EӨ value, which is –3.04V. Lithium has a small atomic size, the highest ionization enthalpy but it is compensated by its high hydration …
Nettet6. feb. 2024 · Li-ion batteries are sensitive to temperature. One unfortunate property of Li-ion batteries is that they’re prone to combustion if they get too hot, and they contain all the necessary elements for self-sustaining a fire. It’s another reason why we shouldn’t become too dependent on Li-ion batteries. NettetThe hydration energy of Li+ ion is very high and as a result of this reduction potential of lithium is very low(E°= –3). So lithium acts as the most powerful reducing agent in …
NettetIn group I, for example, the ionization energies decrease in the order Li > Na > K > Rb > Cs. How do you arrange elements in order of decreasing electron affinity? O>S>N. Which group has the 2nd highest ionization energy? Li Li has the highest IE2 , because to remove the second electron we must break the stable 1s2 noble gas shell.
