Any of the noble gases (in the right-most column of the Periodic Table): helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) radon (Rn), and Hydrogen.
They all have what is called a stable "octet."
See the Related Questions for more information on what the octet rule in chemistry is.

What is the name of a large atom?
Apparently uranium is the largest atom, with 92 protons and 92 electrons.
What the meaning of radioactive?
Radioactive means that an atom is unstable and undergoes radioactive decay, emitting radiation in the form of particles or electromagnetic waves. This process can result in the release of energy and transformation of the atom into a different element.
Nuclear radiation refers to charged particles or energy emitted by an unstable what?
Nucleus
In nuclear fission reactions what causes the atom's nucleus to become unstable?
the absorption of a free-moving neutron by the atom's nucleus
What is an example of unstable equilibrium in sports?
An example of unstable equilibrium in sports is balancing on a balance beam in gymnastics. Athletes must continuously adjust their position to stay on the beam, as any slight movement can cause them to lose balance and fall off.
What makes a atom unstable?
it might not be unstable with anything.......
What are the characteristics of a atom?
A radioactive atom is an atom of an element with an unstable nucleus.
What is an unstable atom?
An unstable atom is an atom that has an imbalance in the ratio of protons to neutrons in its nucleus, making it prone to undergo radioactive decay. This decay results in the emission of particles or energy in order to achieve a more stable configuration. Unstable atoms will continue to decay until they reach a state of stability.
Does an atom become imbalanced with a positive charge?
The stability of the positive ion depends on the atom which removes the electron. As an example, when a sodium atom becomes positive, it is highly stable, on the contrary, when a chlorine atom becomes positive, it is highly unstable.
Is 288 is unstable or reactive atom?
The number 288 does not correspond to an atom as it is not a specific element. Atoms themselves are not considered stable or unstable, but certain isotopes of elements can be unstable and undergo radioactive decay.
What is another term for an atom that is unstable?
isotope
What is the term for an atom that has an unstable nucleus?
radioisotope
What is the term for an atom the decays?
unstable, radioactive
What number of protons does carbon atom become unstable?
Carbon atom contains only 6 protons. It is become unstable when number of neutrons are increasing.
What is the name of a large atom?
Apparently uranium is the largest atom, with 92 protons and 92 electrons.
Atom with an unstable nucelus is called?
It is a radioactive element.
What causes an atom to be stable and unstable?
An atom is stable when its nucleus has a balanced ratio of protons and neutrons, and when its electrons are in filled energy levels. An atom is unstable when it has an imbalance of protons and neutrons in the nucleus, leading to radioactive decay in an attempt to reach a more stable configuration.
