Решение. №9 (с. 64)
Дано:
Энергия испущенного фотона $E = 9,61 \cdot 10^{-19}$ Дж.
Найти:
Изменение заряда атома $\Delta q$.
Решение:
Атом представляет собой систему, состоящую из положительно заряженного ядра и отрицательно заряженных электронов. В обычном состоянии атом электрически нейтрален, так как суммарный положительный заряд ядра равен суммарному отрицательному заряду электронов.
Испускание фотона атомом происходит, когда электрон переходит с более высокого энергетического уровня на более низкий. При этом сам электрон не покидает атом, а лишь меняет свою орбиталь. Фотон — это квант электромагнитного излучения, который является электрически нейтральной частицей, то есть его заряд равен нулю.
Поскольку в процессе испускания фотона атом не теряет и не приобретает заряженные частицы (протоны или электроны), его суммарный электрический заряд остается неизменным в соответствии с законом сохранения заряда.
Следовательно, заряд атома в результате этого процесса не изменится.
Ответ: 4) не изменился.
