What is Ag? Important knowledge about Ag.

Definition of Ag:
Ag is the chemical symbol for the element Silver. The atomic weight of Ag is 107.87 and its average atomic mass is approximately 107.8682(2) u. Pure Ag molecules typically have a simple structure, consisting only of one silver atom. The ion of silver is usually Ag+, which contains 46 electrons and 61 neutrons.

Properties of Ag:
2.1 Physical properties of Ag:
Ag is solid at room temperature, with a bright metallic silver color. Ag has no smell and its pH cannot be determined because it is a solid metal.
2.2 Chemical properties of Ag:
Ag does not react with oxygen at room temperature but can be oxidized at high temperatures. It can also react with sulfur to form Ag₂S.

Common chemical equations of Ag:
Metal Reaction: Ag can react with strong acids like HNO₃.
Acid Reaction: Ag + HNO₃ -> AgNO₃ + NO₂ + H₂O
Non-metal Reaction: Ag + S -> Ag₂S
Reaction with Salt: AgNO₃ + NaCl -> AgCl + NaNO₃

Silver (Ag) Synthesis:
4.1 Laboratory Synthesis of Ag:
Ag can be synthesized from the reaction between nitric acid and metallic silver: Ag + HNO₃ -> AgNO₃ + NO₂ + H₂O
4.2 Industrial Synthesis of Ag:
In industry, Ag is often synthesized from silver ore containing Ag₂S through a process of melting and refining.
