FAQs on Anomalous Properties of Lithium Video Lecture - Inorganic Chemistry for NEET

1. What are the anomalous properties of lithium?
Ans. Lithium exhibits several anomalous properties, including its low density, high specific heat capacity, and high reactivity with water. It also has a high electrochemical potential and is used in batteries.
2. Why is lithium's low density considered an anomalous property?
Ans. Lithium's low density is considered anomalous because it is the lightest metal and has a lower density than expected based on its position in the periodic table. This unique property contributes to its use in lightweight alloys and as a component in aerospace applications.
3. How does lithium's high specific heat capacity make it anomalous?
Ans. Lithium's high specific heat capacity is considered anomalous because it is higher than other alkali metals. This means that lithium can absorb and store more heat energy per unit mass, making it useful in applications where efficient heat transfer is essential, such as in nuclear reactors.
4. What makes lithium's reactivity with water an anomalous property?
Ans. Lithium's reactivity with water is considered anomalous because it is more reactive than other alkali metals in the same group. When lithium comes into contact with water, it reacts vigorously, producing hydrogen gas and forming a strong alkaline solution. This reactivity is due to lithium's low ionization energy, which allows it to readily lose an electron and form a cation.
5. How is lithium's high electrochemical potential an anomalous property?
Ans. Lithium's high electrochemical potential is considered anomalous because it is the most electronegative element among the alkali metals. This property makes lithium an excellent choice for use in batteries, as it can easily donate electrons and undergo oxidation, resulting in a high voltage output. Its high electrochemical potential also contributes to its role as a key component in rechargeable lithium-ion batteries.
