There is nothing "magic" about absolute zero. It's unattainable in practice, but theoretically nothing in particular would "happen" if an atom did achieve that temperature. If you were hoping for an answer like "the electrons would stop moving and collapse into the nucleus", no, sorry, that's not going to happen.
no, absolute zero is only a myth. Temperature is the measurement of thermal energy caused by the movement of the atoms. at absolute zero, atom freezes and it would be impossible to measure its temperature.
what would happen to the current modal of the atom if new information about its is discover in the feature
Isotopes
It would become an atom of a different element. This can only happen during radioactive decay, nuclear fusion, or nuclear fission.
NO! They only split one atom in an Atomic Bomb. think of what would happen if you did it at home!
it could not exist
It would be Deuterium, also called Heavy Hydrogen.
Sodium chloride is formed.
It is the smallest particle
It would become a different element. It could become radioactive.
Then it would not be an atom, but a non-existing Carbon anion (-1, negatively charged)
The atom would have to absorb energy.
