unstable, radioactive
it might not be unstable with anything.......
A radioactive atom is an atom of an element with an unstable nucleus.
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.
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.
Carbon atom contains only 6 protons. It is become unstable when number of neutrons are increasing.
This is the definition of an "isotope".
It is a radioactive element.
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.
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
1, because it will make the atom become unstable.
