In chemical reactions, the group shell is crucial for determining the direction of electron transfer. In redox reactions, the element with a higher tendency to lose electrons (higher electropositivity) will do so, while the element with a greater affinity for electrons (higher electronegativity) will gain them. This principle governs many reactions, including those involved in energy production and materials science.

The work of these rock drilling companies extends beyond the extraction of resources. They also contribute to large-scale civil engineering projects, such as the construction of hydroelectric power stations, highways, and subway systems. For instance, Herrenknecht AG, a German company, specializes in tunnel boring machines, playing a crucial role in the creation of complex underground networks.

Elements are arranged in the periodic table based on their atomic number, which increases from left to right and top to bottom. Within this arrangement, elements are categorized into groups or families with similar chemical properties. These properties largely depend on the number of electrons in the group shell. For instance, oxygen, sulfur, and selenium belong to the same group, known as oxygen group or chalcogens, because they all have six electrons in their outermost shell.
