This discovery enabled people to realize that there was a small, constant particle which is the smallest unit of matter. Even though the atom could not be seen, Democritus recognized its existence sparking thought about it in later years.

Dalton’s atomic theory states that all matter is composed of indivisible, indestructible atoms with distinct properties that determine their characteristics. It formed a basis of understanding for atomic research going forward. His "marble model" portrays the atom as a sphere with the same particles throughout. -
This realization of an atom’s electromagnetic charge was significant to learning about different unknown parts of the atom and how they interact.

This led to the discovery of the proton, majorly contributing to the atomic model by adding to understanding of the nucleus.

After 3 years, the war ended with the Philippines becoming a US territory.

His discovery led to the formation of the “nuclear model”, also known as the “Jimmy Neutron” model which is common today. -
This also allowed him to discover that if electrons jump to a lower-energy orbit, they create light or radiation. His discovery significantly changed the preexisting knowledge of atomic orbits and led to more thinking about them. -
-
This contributed to thinking about the atom by establishing that atomic fields are not what they were previously known to be.
-
His model assumes that the electron takes on wave-like behaviors, and does not follow defined orbits. -
-
-
This started the thinking that both protons and neutrons occupy the nucleus, and that they have roughly the same mass. -
