Answer :
Final answer:
Niels Bohr developed the groundbreaking model of the atom that showcased its internal structure, transforming the field of atomic theory.
Explanation:
The scientist who developed the first model of the atom that showed the structure of the inside of an atom was Niels Bohr.
Bohr's model, introduced in 1913, depicted the atom as a central nucleus containing protons and neutrons, with electrons in circular orbitals at specific distances forming energy levels or electron shells.
This model revolutionized the understanding of atomic structure and laid the foundation for principles in quantum mechanics.
