Nuclear radiation from silicon photocells
8.1: Nuclear Radiation
Marie Curie (1867 - 1934) was a Polish scientist who pioneered research into nuclear radiation (Figure (PageIndex{1})). She was awarded the Nobel Prize in physics in 1903 along with her husband Pierre and Antoine Henri Becquerel for their work on radioactivity. She was awarded a second Nobel Prize in 1911, this time in chemistry, for her ...
11.4: Nuclear Decay
Moreover, if we lose 4 nuclear particles of the original 235, there are 231 remaining. Thus, we use subtraction to identify the isotope of the thorium atom—in this case, (ce{^{231}_{90}Th}). Because the number of protons changes as a result of this nuclear reaction, the identity of the element changes.
