Nuclear Equations GCSE Physics Diversity in Science Teaching Pack
Nuclear equations are used to represent radioactive decay. There are different types of radioactive decay, such as: Alpha ( ) decay Beta ( ) decay
Who developed the theory of beta decay? The Italian physicist Enrico Fermi developed the theory of beta decay in 1933. But some scientists found that their experiments did not match Fermi s theory. Enrico Fermi (1901 1954)
New experiments needed In 1949, the Chinese-American physicist Chien-Shiung Wu did another experiment. She provedthat Fermi s theory of beta decay was right. Wu corrected the errors in previous beta decay experiments. Chien-Shiung Wu (1912 1997)
How do scientific theories and methods develop over time? Science isn t made by individuals. Scientists work together, and build on each other s ideas. Enrico Fermi developed a theory of beta decay. Chien-Shiung Wu used experiments to test the theory, and correct errors.
And whilst were here Scientists from around the world helped develop the physics of nuclear decay. Here are just a few: A person in a lab coat Description automatically generated with medium confidence George Gamow Hideki Yukawa Lise Meitner James A.
