Who proposed the first atomic theory?

  • A.E. Rutherford
  • B.De Broglie
  • C.John Dalton
  • D.D.I. Mendeleev

Answer: C

John Dalton proposed the first atomic theory, in 1808.

His postulates were that matter consists of indivisible atoms, that all atoms of an element are alike in mass and properties, and that compounds form when atoms combine in fixed small whole-number ratios. The theory accounted at once for the laws of conservation of mass and of definite and multiple proportions.
