The chemical symbol for silver is Ag. This symbol comes from the Latin word “Argentum”, which means silver. The name is derived from the Sanskrit word argunas and the Greek argyros, both meaning “shiny” or “white,” reflecting the metal’s bright luster.

Silver is a transition metal with the atomic number 47 and an atomic mass of approximately 107.87 u. It belongs to Group 11 of the periodic table, along with copper (Cu) and gold (Au). These elements are sometimes called the coinage metals because they have historically been used in making coins due to their durability and resistance to corrosion.

Physical and chemical properties of silver:

• 
  

  Appearance: Shiny, white, metallic luster

  
  


• 
  

  Electrical and thermal conductivity: Silver is the best conductor of electricity and heat among all metals

  
  


• 
  

  Malleability and ductility: It can be hammered into thin sheets and drawn into wires

  
  


• 
  

  Reactivity: Silver is relatively stable in air and water but tarnishes when exposed to sulfur compounds, forming black silver sulfide (Ag₂S)

  
  

Uses of silver:

• 
  

  Jewelry and ornaments: Due to its attractive luster and resistance to corrosion

  
  


• 
  

  Electronics: In conductors, electrical contacts, and solar panels because of its superior conductivity

  
  


• 
  

  Photography: Historically used in silver halide films

  
  


• 
  

  Medicine: Silver compounds, such as silver nitrate, have antimicrobial properties and are used in wound dressings

  
  


• 
  

  Coins and currency: Used for centuries as a standard of trade and wealth

  
  

Difference from other options:

• 
  

  Au = Gold

  
  


• 
  

  Sv = No element symbol (invalid)

  
  


• 
  

  At = Astatine, a rare halogen

  
  

Thus, the correct chemical symbol for silver is Ag, and it holds great importance in history, industry, and modern applications.
