As a subject matter expert in chemistry, I can provide an in-depth explanation about the bonding capabilities of beryllium. Beryllium, with the atomic number 4 and symbol Be, is the first element in the second period of the periodic table. It is an alkaline earth metal, and its electronic configuration is [He] 2s². This configuration means that beryllium has two valence electrons in its outermost shell.
The two valence electrons of beryllium are crucial for understanding its bonding behavior. In general, elements tend to form bonds in order to achieve a stable electron configuration, often resembling that of a noble gas. Beryllium, with its two valence electrons, typically seeks to lose or share these electrons to reach the electron configuration of neon, which has a full outer shell with eight electrons.
Given its electronic configuration and the tendency to achieve stability, beryllium can form a +2 oxidation state. This means that it can form two covalent bonds with other atoms. Covalent bonds are formed when atoms share electrons, and in the case of beryllium, it can share its two valence electrons with two other atoms, effectively 'donating' these electrons to form stable molecules.
However, there are some exceptions to this rule. The solubility of beryllium in BeCl₂ suggests a lower valence state. In this case, beryllium does not exhibit its typical +2 oxidation state but rather a lower oxidation state, which is indicative of its ability to form bonds in different ways under specific conditions.
Additionally, there are two neutral beryllium bis(carbene) compounds where the beryllium center has a formal oxidation state of zero. These compounds are unique and showcase the versatility of beryllium in bonding. In these compounds, the beryllium atom does not lose or gain electrons but instead forms bonds through a different mechanism, which is characteristic of its unique electronic structure and the nature of carbene ligands.
In summary, while beryllium is known for its +2 oxidation state and the ability to form two covalent bonds, there are instances where it can exhibit different oxidation states and bonding behaviors. This highlights the complex nature of chemical bonding and the importance of understanding the underlying principles of electron sharing and oxidation states.

The two valence electrons give beryllium a +2 oxidation state and thus the ability to form two covalent bonds; the only evidence of lower valence of beryllium is in the solubility of the metal in BeCl2, and in two neutral beryllium bis(carbene) compounds in which the Be center bears a formal oxidation state of zero.
