Современные атомные теории, основанные на атомной модели, располагают массу и положительный заряд атома в центральном ядре, окруженном двигающимися электронами. ядра состоят из нейтронов и протонов. нейтроны имеют массу приблизительно в одну шестнадцатую массы атома кислорода и нулевой электрический заряд. протон весит немного меньше нейтрона и примерно эквивалентен массе водорода h . элементы разделяются по различающемуся количеству протонов и нейтронов в ядрах, количество протонов эквивалентно атомному номеру, водород имеет номер один, гелий два и так далее.   электрон это наименьшая известная неделимая частица с электрическим зарядом. ранние экспериментаторы преуспели в измерении отношения заряда к массе, и в 1910 заряд был впервые измерен, таким образом определяя эти характеристики электрона. электрон выявляет двойственные качества, временами проявляя качества вещества, а в других экспериментах требуют признания у него волновых качеств для правильного объяснения феномена.
