Anomalous behaviour of lithium and beryllium

Lithium and beryllium exhibit anomalous behavior due to their small size and unique electronic configurations.

Lithium is the lightest metal and has a very low melting and boiling point compared to other metals. It is also the only metal that can float on water. This is due to its low density and the fact that it reacts with water to produce hydrogen gas.

In terms of electronic configuration, lithium has only one valence electron in its outer shell, which gives it similar properties to both metals and nonmetals. As a result, lithium exhibits properties that are not typical of other alkali metals. For example, it has a higher electronegativity than other alkali metals and a smaller atomic radius. These unique properties make lithium an important element in many industrial applications, including batteries, ceramics, and nuclear power.

Beryllium also exhibits anomalous behavior due to its small size and unique electronic configuration. It is the lightest member of the alkaline earth metals and has a very high melting point compared to other metals. Beryllium is also very hard and brittle, making it difficult to work with.

In terms of electronic configuration, beryllium has two valence electrons in its outer shell, which makes it more like a nonmetal than a metal. It has a small atomic radius and a high ionization energy, which makes it difficult to remove electrons from beryllium atoms. This unique electronic configuration gives beryllium some special properties, such as its ability to form strong covalent bonds and its high resistance to corrosion.

Overall, the anomalous behavior of lithium and beryllium can be attributed to their small size and unique electronic configurations, which give them properties that are different from other elements in their respective groups.
