Difference Between Nickel and Silver

May 7, 2018 Posted by Madhu

The key difference between nickel and silver is that the melting point of nickel is around two times higher than the melting point of silver. Though chemically different, both these metals are lustrous and look somewhat similar. However, unlike silver, nickel has a slight golden tinge.

Nickel and silver are two chemicals that fall into the category of metals. Moreover, both these chemical elements are in the d block of the periodic table of elements.

What is Nickel?

It is a chemical element having the atomic number 28 and the chemical symbol Ni. It resembles silver because both have a lustrous metallic appearance. However, unlike silver, this has a slight golden tinge. Some important chemical facts about nickel are as follows.

  • Atomic number = 28
  • Atomic mass = 58.69 amu
  • Electron configuration = [Ar] 3d84s2
  • Physical state = solid at room temperature
  • Position in the periodic table = group 10, period 4 (d block)
  • Melting point = 1455°C
  • Boiling point = 2913°C
  • Isotopes = Ni-58, Ni-60 and Ni-62 are the key isotopes

In general, nickel resists corrosion even at high temperatures. Moreover, it is a very ductile metal with a high ability to stretch into a thin-wire like structure without breakage. At room temperature, nickel has magnetic properties. Further, this metal is useful in forming different alloys.

What is Silver?

It is a chemical element having the atomic number 47 and the chemical symbol Ag. The symbol Ag comes from the Latin word Argentum meaning silver. The metal is highly unreactive; thus, it occurs in nature as a pure metal. Moreover, it has a characteristic, lustrous appearance. Some important chemical facts about silver are as follows:

  • Atomic number = 47
  • Atomic mass = 107.86 amu
  • Electron configuration = [Kr] 4d105s1
  • Physical state = solid at room temperature
  • Position in the periodic table = group 11, period 5 (d block)
  • Melting point = 961.7oC
  • Boiling point = 2162 °C
  • Isotopes = Ag-107 and Ag-109 are the key isotopes

Silver is corrosion resistant due to its unreactive nature. Moreover, it has many applications in the production of jewelry, electronics (to make conductors and electrodes), catalysis (it is a good catalyst for oxidation reactions), silver nanoparticles, etc.
