Bohr Model of the Atom of Hydrogen

**Symbol:** H **Atomic number:** 1 **Relative atomic mass:** 1.008 **Description:** Hydrogen is the lightest and simplest chemical element. It is a colorless, odorless and tasteless gas. Although highly flammable, hydrogen does not support combustion on its own. **Applications:** Hydrogen is extensively used as an energy source (e.g., rocket fuel), a reducing agent in chemical processes (e.g., ammonia synthesis and organic synthesis), and in metallurgical applications. **Occurrence:** Elemental hydrogen (H) is rare on Earth but is the most abundant element in the universe. On Earth, it is mainly found in compounds, especially in water and various organic molecules, making it an essential biogenic element. According to Bohr's atomic model, the electron in a hydrogen atom moves in a fixed, circular orbit with constant energy. A hydrogen atom consists of one positively charged proton and one negatively charged electron. The proton is located in the nucleus, while the electron moves around the nucleus in a defined circular path.
