Question

According to Dalton's atomic theory, atoms can neither be created nor be destroyed in a chemical reaction.

• A. True
• B. False

Answer 1

The correct option is A True

• According to Dalton's atomic theory, all matter is made up of very tiny particles called atoms. Atoms are indivisible particles that cannot be created or destroyed in a chemical reaction.
• It is based on the law of conservation of mass.
• So, in a chemical reaction, the mass of reactants is always equal to the mass of products.

Dalton's atomic theory

• ​All matter is made up of tiny, indivisible particles called atoms.
• All atoms of a specific element are identical in mass, size, and other properties. However, atoms of different element exhibit different properties and vary in mass and size.
• Atoms can neither be created nor destroyed. Furthermore, atoms cannot be divided into smaller particles.
• Atoms of different elements can combine with each other in fixed whole-number ratios in order to form compounds.
• Atoms can be rearranged, combined, or separated in chemical reactions.

Hence, The given statement, atoms can neither be created nor be destroyed in a chemical reaction.is true
