neutral gamma rays do not bend at all <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; mso-fareast-font-family: 'Times New Roman';"> Atomic Theory: He discovered that uranium absorbed the suns energy and created x-rays. He worked with Pierre and Marie Curie. Each of them won the Nobel Prize in Physics. No problems with model, but his theory wasn’t able to be used until modern day.
