Question
“Atom as an indestructible entity” was proposed by?
- Einstein
- Thomson
- Bohr
- Dalton
Both A and C
Hint:
A scientist proposed that atoms cannot be broken into smaller particles.
The correct answer is: Dalton
Both A and C
- Dalton proposed that the “Atom is an indestructible entity”.
- According to Dalton's atomic theory, all matter around us is composed of atoms. This atom is the smallest particle to ever exist in the universe.
- The atom cannot be broken down into other discrete particles, which means that it is impossible to break the atom into smaller units.
Dalton's atomic theory does not account the presence of isotopes.
