yes a great deal indeed
True. The model of the atom has evolved significantly since the 1930s, moving from the Bohr model to the quantum mechanical model. The discovery of subatomic particles, such as protons, neutrons, and electrons, led to a more complex understanding of the atom's structure.
thay hAve chANged alot
Erm the 1930s is an intresting period both stylistically anel historically.
yes
nothimg

There has been more and more observations about the atom that has changed it since then. They revised it to explain the observations.
Very much so.
The electron was discovered by J.J. Thomson in 1897, when he discovered particles inside the atom that contains a negative electric charge. Since then, scientists have learned much more about electrons, and the way they are imagined has changed as well. Niels Bohr established that there was a structure to the way electrons are laid out within the atom, and this discovery has changed the study of physics.
THe required minimum age for US president is 35 years old and has never changed since the Constitution took effect in 1787.
When the number of protons is changed in an atom, the result is the formation of a NEW ELEMENT.
Depends on the sentence. "The 1930s were the highlight of American culture." - subject, noun. "Wow, your jeans are sooo 1930s." - predicate adjective, adjective "I haven't partied that hard since the 1930s." - not sure, but a noun. "How were the 1930s?" - predicate nominative, noun.
