Matter is comprised of small particles called atoms. All four statements are part of Dalton's original atomic theory. Different elements have atoms of different masses and properties. Atoms of the same element have the same size, mass, and structure. Atoms cannot be created or destroyed in a chemical reaction.

Answer 1

Answer:

The all 4 the given statements are part of Dalton's atomic theory.

Explanation:

Dalton's postulates or Dalton's atomic theory:

• Matter is made up of small particles termed as atom.
• Atoms are indivisible particle.
• Atoms of different element have different masses and properties.
• Atoms of the same element have the identical size, mass, and structure.
• During chemical reaction, rearrangement of atoms takes place.
• Atoms of different different combines together to form new compounds in simple whole number ratio.
