Which of the following statements correctly orders the historical development of atomic models?
ABohr → Rutherford → Thomson → Dalton
BDalton → Rutherford → Thomson → Bohr
CDalton → Thomson → Rutherford → Bohr
DThomson → Dalton → Rutherford → Bohr
Answer & Solution
Correct answer: C. Dalton → Thomson → Rutherford → Bohr
Dalton (1808, atomic theory — indivisible atoms) → Thomson (1898, plum pudding — electrons embedded in positive sphere) → Rutherford (1911, planetary — nucleus with orbiting electrons) → Bohr (1913, quantised orbits). Each model improved on its predecessor based on new experimental evidence.
