Which of the following options is correct with respect to atomicity?
Oxygen, Ammonium Chloride, Sulphuric acid.
Oxygen (O2) has 2 Oxygen atoms,
Ammonium chloride (NH4Cl) has 1 nitrogen, 4 hydrogen and 1 chlorine atom.
Sulphuric acid (H2SO4) has 2 hydrogen, 1 sulphur and 4 oxygen atoms.
Atomicity of oxygen(O2), ammonium chloride (NH4Cl) and sulphuric acid (H2SO4) are 2, 6, and 7 respectively.
So, the order of atomicity is Oxygen < Ammonium chloride < Sulphuric acid
