Homework answer is:-
No,not all the postulates of dalton's atomic theory are correct
Correct laws are as follows:-
1) Discovery of isotopes
2)An atom is divisible
3)The atoms are not divided in the simple ratio as stated by Dalton's atomic theory for example atoms of sugar are in the ratio 12:22:11.
4)Atoms of different elements may have same mass for example:-Atomic mass of calcium and argon are same that is 40.
Thanku mam the session was amazing 😍
Mam start mole concept please 🥺
17:35 No all postulates are not correct because of the following reasons
1) atoms can further divided into electorns ,protons and neutrons
2) the concept of isotopes proven the second postulate wrong
3) in biomolecules and organic compounds 3rd postulate not valid
Superb lecture mam 😊😊
Nice lecture
Mam schedule ki pronunciation sheduule hoti h aur c silent hota h

➡️Not all postulates of daltons theory was correct
Dalton stated that an atom could be no divided into smaller pieces
❌This was proven wrong❌
Reason✅ as subatomic particles of atoms are exist such as neutrons protons and electrons
