John Dalton's Atomic Theory Quiz

John Dalton's Atomic Theory

• According to John Dalton's atomic theory, matter is composed of small indivisible particles called atoms, which cannot be created or destroyed in a chemical reaction.
• Dalton believed that atoms of the same element are identical in mass, properties, and behavior.

Elements

• Dalton believed that each element is composed of only one type of atom, and that atoms of different elements have different masses and properties.

Contribution to Atomic Theory

• John Dalton's contribution to the atomic theory was the development of the modern atomic theory, which provided a foundation for understanding the structure of matter.
• Dalton's theory explained the law of definite proportions, which states that a chemical compound always contains the same proportion of elements by mass, regardless of its source.
