Question

'Atoms of most elements are not able to exist independently ' name two atoms which exist as independent atom?

Answer 1

The atoms of only a few elements called noble gases (Such as helium, neon, argon and kryton, etc.) are chemically unreactive and exist in the free state or independently. Atoms of most of the elements are chemically very reactive and do not exist in the free state or independently.

Answer 2

'Atoms of most elements are not able to exist independently' but some of the elements exist independently these are:

• Helium, Neon, Argon, Krypton, etc. exists as independent atoms.
• These elements are called Noble gases.
• They have fulfilled stable electronic configurations so they exist independently.
• They have 0 valencies.
• They are chemically inert.
• They exist in a free state.

Hence, Helium, Neon, Argon, Krypton, etc. exists as independent atoms.
