The only such elements are the Noble Gases (He, Ne, Ar, Kr, Xe, Rn) (that is helium, neon, argon, krypton, xenon and radon)
The noble gases, group 18, exist in nature as isolated atoms.
No.
Bohrium is a synthetic radioactive element. It does not exist in nature.
You really need to look up what those words mean, because the question you have asked makes no sense.EVERY atom is an isotope.The atoms of any given element may be any of several isotopes, though some of them may not exist in nature, or may exist in nature only in trace quantities.
An 'atom' is the smallest unit that ANY element can be divided up into. An 'atom' of silver is the smallest piece of silver that there can be, similarly an 'atom' of oxygen is the smallest bit of oxygen that can be. Thus all elements are made of 'atoms'.
Technetium is an artificial chemical element; only ultratraces exist in nature in uranium ores.
No. It is a Atomic element because it exist in nature with single atoms as their basic unit.
No. It is a Atomic element because it exist in nature with single atoms as their basic unit.
No.
I would say the noble gases since as gases their atoms are isolated and they do not form diatomic molecules like all the other gaseous elements.
Americium is an artificial element, don't exist in the nature.
Americium is an artificial chemical element and don't exist in the nature.
The external shell of electrons is completely filled.
It is a man-made element and, due to its high radioactivity does not exist in nature.
as, u all know element's exist in a free state in nature, like gold, in same way the atoms exists independently in nature, as, they are only the smallest particle no, more further can be divide, so, as, it is independent in nature.
Bohrium is a synthetic radioactive element. It does not exist in nature.
Copernicium is a synthetic radioactive element. It does not exist in nature.
Darmstadtium is a synthetic radioactive element. It does not exist in nature.
