Which of the following does not illustrate the anomalous properties of...
Explanation:
The anomalous properties of lithium:
Lithium (Li) is the first element in Group 1 of the periodic table, also known as the alkali metals. It exhibits some anomalous properties that distinguish it from the other elements in its group.
High melting and boiling point:
Li has a relatively high melting point and boiling point compared to the other alkali metals (sodium, potassium, rubidium, and cesium). This is due to the presence of strong metallic bonding in lithium, which is a result of its small atomic size and high charge density. The strong metallic bonding requires more energy to break, resulting in higher melting and boiling points.
Formation of nitride:
Li forms a nitride compound, Li3N, unlike the other group 1 metals. Nitrogen is a highly electronegative element and typically forms an anion (N3-) in compounds. The formation of Li3N indicates the ability of lithium to form stable compounds with nitrogen.
Hydration of Li ions:
Li ions and its compounds are more heavily hydrated compared to the rest of the group 1 elements. This is due to the small size of the Li ion, which allows it to attract a larger number of water molecules. The high hydration energy of Li ions contributes to its unique properties in solution, such as increased solubility and conductivity.
Lithium is much softer:
The statement that does not illustrate the anomalous properties of lithium is option B, which states that "Li is much softer than the other group I metals." This is not an anomalous property of lithium because it is consistent with the trend observed in the alkali metals. As we move down the group, the atomic size increases, leading to weaker metallic bonding and softer metals. Therefore, lithium being softer than the other alkali metals is expected and not an anomaly.
In summary, the anomalous properties of lithium include its higher melting and boiling points, the formation of nitride compounds, and the stronger hydration of its ions. The statement that lithium is much softer than the other group 1 metals is not an anomalous property as it aligns with the trend observed in the group.
