D
Explanation:
An atom can be considered unstable in one or two ways. If it pickes up or loses an electron,it becomes electrically charged and highly reactive.Intabability can also occur in the nucleus when the number of protons and neutrons is unbalanced.

My freind the best anwer would probably be B
If Thomson’s model of the atom were correct, Rutherford should have seen a complete reflection of those particles when fired at the foil. Those particles would have hit a solid object (Thomson model) and would have been reflected back at the emitter. However, Rutherford discovered that most of those particles passed through the sheet, either continuing straight through or having the angle change a small amount (bouncing off the nucleus). Only a small number of the particles were reflected back, having hit the nucleus straight on. This led him to believe that there was a small, dense portion of the atom that resided within a larger, emptier space.
