• A. Reorganisation of atoms in chemical reactions
• B. ldentical properties of all atoms of given element
• C. The reason for combining of atoms
• D. Formation of compounds from the combination of elements in a fixed ratio
• E. Matter consists of individual atoms

Answer 1

Answer: (C)

The reason for combining of atoms

Answer 2

The correct answer is (C): The reason for combining of atoms

Postulates of Dalton's atomic theory:

1. All matter consists of indivisible particles called atoms.
2. Atoms of the same elements are similar in shape and mass but differ from the atoms of other elements.
3. Atoms cannot be created or destroyed.
4. Atoms of different elements may combine with each other in fixed, simple, whole-number ratios to form elements and compounds.
5. The atom is the smallest unit of matter that can take part in a chemical reaction.
