The velocity of an electron in the first Bohr orbit of a hydrogen atom is 2.19 × 106 m/s.
Understanding the Bohr Model and Electron Velocity
The Bohr model is a simplified model of the atom that depicts electrons orbiting the nucleus in specific circular paths, or orbits. In this model, electrons in these orbits are assumed to possess a certain velocity. Specifically, when discussing the first Bohr orbit, we are referring to the orbit closest to the atom's nucleus, which is the lowest energy state for the electron.
Key Features of the First Bohr Orbit
- Lowest Energy Level: The first Bohr orbit represents the ground state or lowest energy level for an electron in an atom.
- Specific Velocity: According to calculations, the electron in this orbit possesses a particular velocity.
- Quantized Energy: The Bohr model postulates that electrons can only occupy certain orbits with specific energy levels, and these energy levels are quantized.
