Question

Why don't an atom exist independently? what will happen to it's properties if it exists independently?

Solution

Atoms can not exist independently. This is because atoms accept electrons or donate electrons to form stable octet fulfilled electronic configurations and this is only possible by the formation of molecules. So atoms cannot exist alone. But only inert gases already have octet fulfilled configurations so they can exist as atoms.

Common Properties

  • Fairly nonreactive.
  • Complete outer electron or valence shell (oxidation number = 0)
  • High ionization energies.
  • Very low electronegativities.
  • Low boiling points (all monatomic gases at room temperature)
  • No color, odor, or flavor under ordinary conditions (but may form colored liquids and solids)
