Hydrogen has electronic configuration 1sIts electronic configuration is similar to the outer electronic configuration (ns) of alkali metals, which belong to the first group of the periodic table. Hydrogen therefore has resemblance to alkali metals, which lose one electron to form unipositive ions. Like alkali metals, hydrogen forms oxides, halides and sulphides.

Hydrogen Forms Oxides, Halides, and Sulphides

Introduction:
Hydrogen is a unique element in the periodic table as it has properties of both nonmetals and metals. It is found in Group 1 of the periodic table, along with alkali metals such as lithium, sodium, and potassium. Like alkali metals, hydrogen also forms various compounds, including oxides, halides, and sulphides.

Oxides:
- Hydrogen can form oxides by combining with oxygen. The most common oxide of hydrogen is water (H2O). Water is a vital substance for life and is found in abundance on Earth.
- Hydrogen can also combine with oxygen to form other oxides such as hydrogen peroxide (H2O2) and water ice (H2O in solid form).
- These oxides have various applications, such as water for hydration, hydrogen peroxide as a disinfectant, and water ice in various industrial processes.

Halides:
- Hydrogen can react with halogens (Group 17 elements) to form halides.
- For example, hydrogen can combine with chlorine to form hydrogen chloride (HCl), a colorless and highly acidic gas.
- Hydrogen fluoride (HF), hydrogen bromide (HBr), and hydrogen iodide (HI) are other examples of halides formed by the reaction of hydrogen with halogens.
- These halides have various applications in industries, such as hydrogen chloride for the production of PVC and hydrogen fluoride for etching glass.

Sulphides:
- Hydrogen can also form sulphides by reacting with sulphur.
- Hydrogen sulphide (H2S) is a common example of a sulphide formed by the combination of hydrogen and sulphur.
- Hydrogen sulphide is a colorless gas with a strong odor of rotten eggs and is commonly found in natural gas and volcanic emissions.
- It has various applications, such as in the production of sulfuric acid and as a precursor for metal sulphides.

Conclusion:
In conclusion, hydrogen, like alkali metals, forms various compounds including oxides, halides, and sulphides. These compounds have numerous applications in different industries and play essential roles in various chemical processes. Understanding the properties and reactivity of hydrogen is crucial for studying its diverse range of compounds and their applications.
