Verified step by step guidance

1. Step 1: Understand the historical timeline of atomic theory development by identifying the key contributions of each scientist.
2. Step 2: Recall that John Dalton proposed the first modern atomic theory in the early 19th century, establishing atoms as indivisible particles.
3. Step 3: Recognize that J.J. Thomson discovered the electron in 1897, leading to the plum pudding model of the atom.
4. Step 4: Note that Ernest Rutherford conducted the gold foil experiment around 1911, discovering the atomic nucleus and proposing a nuclear model.
5. Step 5: Remember that Niels Bohr developed his model of the atom in 1913, introducing quantized electron orbits around the nucleus.
