Group 16 elements, also known as the chalcogens, have varying reactivities towards hydrogen.
Oxygen (O) and sulfur (S) are non-metals and tend to form covalent bonds with hydrogen. Oxygen can form water (H2O) with hydrogen, while sulfur can form hydrogen sulfide (H2S) or sulfuric acid (H2SO4) depending on the reaction conditions.
On the other hand, selenium (Se) and tellurium (Te) are metalloids and can exhibit both metallic and non-metallic properties. These elements can also form covalent bonds with hydrogen, but they are less electronegative than oxygen and sulfur, making them less reactive towards hydrogen.
In general, the reactivity of group 16 elements towards hydrogen increases as you move down the group. However, their reactivity towards hydrogen is still relatively low compared to the alkali metals and alkaline earth metals.

How is Required p-Block Elements Group 16 Reactivity towards hydrogen
The reactivity of p-block elements in group 16 towards hydrogen is determined by their electronic structure and the nature of the bond that is formed when they react with hydrogen.
Oxygen (O) has six valence electrons and is highly electronegative. When it reacts with hydrogen, it forms a covalent bond in which oxygen gains two electrons and hydrogen gains one electron. This bond is strong and stable, making oxygen highly reactive towards hydrogen.
Sulfur (S) has six valence electrons like oxygen but is less electronegative. Sulfur can react with hydrogen to form hydrogen sulfide or sulfuric acid, depending on the reaction conditions. The nature of the bond formed between sulfur and hydrogen is similar to that of oxygen and hydrogen, but it is generally weaker and less stable.
Selenium (Se) and tellurium (Te) have similar electronic structures to sulfur, but they are less electronegative. When these elements react with hydrogen, they form covalent bonds that are weaker and less stable compared to those formed by oxygen and sulfur.
The reactivity of group 16 elements towards hydrogen increases as you move down the group. This is due to the increasing atomic radius, which makes the valence electrons more available for bonding with hydrogen. As a result, polonium (Po), the heaviest element in the group, is expected to be the most reactive towards hydrogen.
Overall, the reactivity of p-block elements in group 16 towards hydrogen is determined by their electronic structure, atomic radius, and the nature of the bond that is formed when they react with hydrogen.
Nomenclature of p-Block Elements Group 16 Reactivity towards hydrogen
The nomenclature of p-block elements in group 16 follows the same naming convention as other elements in the periodic table. Each element is assigned a unique name and symbol based on its atomic number and electronic configuration.
The names of the p-block elements in group 16 are:
- Oxygen (O) – atomic number 8
- Sulfur (S) – atomic number 16
- Selenium (Se) – atomic number 34
- Tellurium (Te) – atomic number 52
- Polonium (Po) – atomic number 84
These names are derived from various sources, including Greek and Latin, and often reflect the properties or characteristics of the element. For example, the name “oxygen” comes from the Greek words “oxys” meaning “acid” and “gennao” meaning “I generate”, reflecting its ability to form acidic compounds.
The symbols for these elements are derived from their names. For example, the symbol “O” is derived from the name “oxygen”, while the symbol “S” is derived from the Latin word “sulfur”.
Overall, the nomenclature of p-block elements in group 16 follows the same conventions as other elements in the periodic table and is based on their unique properties and characteristics.
Case Study on p-Block Elements Group 16 Reactivity towards hydrogen
One interesting case study related to p-block elements in group 16 and their reactivity towards hydrogen is the development of metal chalcogenide materials for hydrogen storage.
Hydrogen is considered a promising alternative to fossil fuels for clean energy generation, but its use is limited by the lack of efficient and safe storage methods. One approach to address this challenge is to use metal chalcogenides, which have high hydrogen adsorption capacities and can store hydrogen in a stable and reversible manner.
Metal chalcogenides are materials that contain chalcogen elements (sulfur, selenium, tellurium) and a metal element (such as copper, silver, or nickel). These materials can be synthesized using various methods, such as solvothermal synthesis or chemical vapor deposition, and their properties can be tuned by adjusting the composition, morphology, and structure.
One example of a metal chalcogenide material for hydrogen storage is copper sulfide (CuS), which has a high hydrogen adsorption capacity and can store hydrogen at room temperature and low pressure. When CuS is exposed to hydrogen, the sulfur atoms in the material form weak chemical bonds with hydrogen, allowing it to be adsorbed and stored.
Other metal chalcogenides, such as copper selenide (CuSe) and copper telluride (CuTe), have also been studied for their hydrogen storage properties. These materials exhibit high hydrogen adsorption capacities and can store hydrogen at a range of temperatures and pressures.
The development of metal chalcogenide materials for hydrogen storage is an example of how the reactivity of p-block elements in group 16 towards hydrogen can be harnessed for practical applications. This approach has the potential to provide a safe and efficient method for storing hydrogen, which could enable its widespread use as a clean energy source.

Electronic Structure:
The electronic structure of p-block elements in group 16 plays a crucial role in their reactivity towards hydrogen. Oxygen has six valence electrons and is highly electronegative, making it very reactive towards hydrogen. When oxygen reacts with hydrogen, a covalent bond is formed in which oxygen gains two electrons and hydrogen gains one electron.
Sulfur, selenium, and tellurium have similar electronic structures to oxygen, but their electronegativities decrease as you move down the group. This makes their bonds with hydrogen weaker and less stable than those formed by oxygen. Polonium, the heaviest element in the group, is expected to be the most reactive towards hydrogen due to its large atomic radius and availability of valence electrons.
Hydrogen Storage:
One promising application of p-block elements in group 16 and their reactivity towards hydrogen is in the development of materials for hydrogen storage. Metal chalcogenides, which contain chalcogen elements (such as sulfur, selenium, and tellurium) and a metal element, can store hydrogen in a stable and reversible manner.
Copper sulfide (CuS), copper selenide (CuSe), and copper telluride (CuTe) are examples of metal chalcogenides that have high hydrogen adsorption capacities and can store hydrogen at room temperature and low pressure. The weak chemical bonds formed between sulfur, selenium, and tellurium atoms in these materials and hydrogen allow for efficient hydrogen storage.
Energy Generation:
Another potential application of p-block elements in group 16 and their reactivity towards hydrogen is in the production of clean energy. Hydrogen is considered a promising alternative to fossil fuels for energy generation, and its use can be facilitated by the development of efficient and safe hydrogen storage methods.
Metal chalcogenides, such as copper sulfide, could be used to store hydrogen for fuel cell applications. Fuel cells generate electricity by combining hydrogen and oxygen, producing only water and heat as byproducts. Metal chalcogenides could provide a safe and efficient method for storing hydrogen for use in fuel cells.
Conclusion:
The reactivity of p-block elements in group 16 towards hydrogen has significant implications for a variety of applications, from energy storage to materials science.
