James Chadwick was a British physicist born in 1891 who is known for discovering the neutron. He received several honors for his work, including the Nobel Prize in Physics in 1935. Chadwick served in World War I and was a prisoner of war. He also participated in the Manhattan Project during World War II. Chadwick's model of the atom focused on neutrons, differing from Niels Bohr's model which depicted electrons in rings. Both models showed the structure of the atom but represented it differently.

6. 2 intersting facts
James Chadwick was captured and
taken prisoner to a concentration
camp during world war 1
In 1919 he created the first
artificial nuclear transparent

7. What was happening in the world
James Chadwick was involved in World War 1
and 2. And in World War 2 he was part of the
Manhattan Project. The Manhattan Project was
the creation of atomic bombs.

8. Visual comparison of the atomic model
Chadwicks Model
Bohr’s Model

9. Differences Between the two models
The bohr model was focusing mainly
on behavior, versus Chadwicks who
was focusing on neutrons.

10. Similarities between the two models
Both models are showing the
electrons, the bohr model just has
many rings as the chadwick model
has one.
