Question

drawbacks of dalton atomic theory ?

Answer 1

Explanation:

Drawbacks of Dalton's atomic theory:

1. Atom can be divided into subatomic particles that is electron , proton and neutrons.
2. Atoms of same element sometimes differ in mass and sizes. These diff rents types of same elements are named as isotopes.
3. Atoms of different elements differ in all aspects but calcium and argon has same atomic mass.These types of atom are termed as isobars.
4. According to him elements combines with each other in whole number to form a compounds which was not observed in complex organic molecules.
5. His theory was not able to explain existence of allotropes.

Answer 2

Answer:

Explanation:

the drawbacks of Dalton's atomic theory are .

He told that atoms can not be divided but atom is made up of subatomic particles like electrons protons and neutrons.

He also told that will also said that elements are same in mass and properties but after the discovery of isotopes it was proved wrong because I to isotopes are atoms of same element having same atomic number the different mass number that can also said that atoms of different elements are different in mass and properties but after the discovery of isobars it was proved wrong because I subah atoms of different elements having different atomic number but same mass number
