Can an atom exist independently
WebDoes helium atom exist independently? 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. WebAnswer: (a) Atoms of some elements are not able to exist independently. For such elements atoms form molecules and ions. In case of metals and inert gases atoms can exist independently. (b) The number of atoms constituting a molecule is known as its atomicity. E.g.,O 3 → atomicity is 3. O 2 → atomicity is 2.
