1 янв 1932 г. - James Chadwick's Atomic Theory
Описание:
In 1932, James discovered the neutron. While experimenting with beryllium atoms with alpha particles, an unknown radiation was produced. Chadwick concluded this radiation as being composed of particles with a neutral electrical charge and the approximate mass of a proton. The neutrons were very hard to find because it did not repel the protons when it was in the atom.Добавлено на ленту времени:
