The major change in the modern atomic model involved transitioning from Dalton's indivisible unit theory to the understanding of subatomic particles and the development of quantum theory.
One major change in the development of the modern atomic model was the transition from the old theory of atoms as indivisible units (Dalton's model) to the current understanding of atoms being composed of subatomic particles like protons, neutrons, and electrons.
This shift in thinking led to the quantum theory that describes the behavior of particles at the atomic and subatomic levels, challenging the traditional notions of classical physics.
Scientists like Schrodinger, Heisenberg, Born, and others contributed significantly to the development of quantum theory, marking a pivotal advancement in atomic science.
