Bohr Radius

The Bohr radius is a fundamental physical constant that represents the average distance between the nucleus and the electron in a hydrogen atom in its ground state, according to the Bohr model of the atom.

• 
  

  Its value is approximately 5.29177 × 10⁻¹¹ meters (about 0.529 angstroms).

  
  
• 
  

  Named after physicist Niels Bohr, who introduced the model in 1913.

  
  
• 
  

  It sets a natural length scale in atomic physics and quantum mechanics.

  
  
• 
  

  Used to describe atomic sizes and electron orbitals.

  
  

Key facts:

• 
  

  Bohr radius ≈ 5.29 × 10⁻¹¹ m

  
  
• 
  

  Represents the typical size of a hydrogen atom’s electron orbit

  
  
• 
  

  Fundamental to quantum physics and atomic structure

  
  

The Bohr radius is essential for understanding atomic dimensions and quantum behavior of electrons.

Long Reed

The long reed is an old English unit of length used primarily in measuring land, especially in agriculture and surveying. It is traditionally equal to 16.5 feet or 5.03 meters.

The long reed was used alongside other units like the rod, pole, and perch, often interchangeably, to measure distances and plot boundaries.

Key points:

• 
  

  1 long reed = 16.5 feet ≈ 5.03 meters

  
  
• 
  

  Used historically in land measurement and agriculture

  
  
• 
  

  Equivalent or similar to the rod, pole, or perch

  
  
• 
  

  Important in English customary measurement systems

  
  

Though obsolete now, the long reed is part of the rich history of traditional English measurement units.
