Hi buddy✌️

Atom - An atom is the smallest particle which retains all its properties is element. An atom does not exist in free state of expect in a noble gas. Expect some of noble gas,other atoms are highly reactive. Atom does not have a chemical bond.An atom is no longer indivisible ( after the discovery of electron,proton & neutron). Atoms of the same element may have different atomic mass ( discovery of isotopes). Atoms of different elements may have same atomic masses (discovery of isobars). Atoms of one element can be transmitted in two atoms of other elements. In our other words atom is no longer indestructible.( discovery of artificial transmutation).
