One fourth
1, because it will make the atom become unstable.
Radioactivity results from unstable elements. This means the amount of protons in the nucleus of the atom is not equal to the amount of electrons in the outer shells of the atom.
it might not be unstable with anything.......
When a large unstable atom splits into two or more smaller atoms, it is called nuclear fission. This process releases a large amount of energy and can result in a chain reaction if not properly controlled.
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.
