The source of alpha particles was placed in a chamber with a built-in screen in one of the walls, which glowed under the impact of charged particles. When filling the chamber with nitrogen, flashes of light appeared on the screen. As a result of the experiments, Rutherford suggested that the screen glows under the influence of some charged particles emitted from the nitrogen atom when alpha particles collide with it.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
