Answer 2

Dolton’s atomic theory

1) elements are made of extremely small particles called atoms. 2) these elements will be identical in size, mass and other properties. 3) atoms cannot be destroyed or created. 4) atoms of different elements combine in simple whole number ratios to form chemical compound.

Limitations of this theory.

Democritus's ideas were not helpful in explaining chemical behavior because they lacked experimental support.
