Dalton’s Atomic Theory
All elements are composed of tiny indivisible particles called atoms.
All atoms of the same element are identical.
Atoms of different elements are different(they have different sizes, masses, chemical properties, etc.).
Atoms of different elements can combine with each other in simple whole number ratios to form compounds. (Law of Definite Proportions).
Chemical reactions occur when atoms are separated, joined, or rearranged. However, atoms of one element are NOT changed into atoms of another element by a chemical reaction. (Law of Conservation of Mass).
