Dalton's atomic theory and it's limitation
Answers
Answer:
The theory that matter consists of indivisible particles called atoms and that atoms of a given element are all identical and can neither be created nor destroyed. Compounds are formed by combination of atoms in simple ratios to give compound atoms (molecules).
The main drawbacks of Dalton's Atomic Theory are- (i) It could explain the laws of chemical combination by mass but failed to explain the law of gaseous volumes. (ii) It could not explain whyatoms of different elements have different masses, sizes, valencies, etc.
Answer:
Acc. to it
☆Matter is made up of extremely small particles called atoms.
☆Atoms of same element are identical in size shape and atomic mass.
☆Atoms of different elements are different in all respect.
☆Atoms of same or different elements are combined together to form different compounds called molecules.
☆When atoms combined with each other to form molecules, they have simple or same multiple proportion.
Atoms can neither be created nor be destroyed.
