Question
Which model concludes that the “electron is the constituent of all kinds of atom.”
- Rutherford atomic model
- Thomson’s model of atom
- Both A and B
- All the above
Hint:
Thomson's atomic model says that all the atoms have electrons as subatoms.ic particles
The correct answer is: Thomson’s model of atom
- J J Thomson in the year 1900 conducted experiments with cathode ray tubes.
- They found that the cathode tubes emit tiny particles with a negative charge and concluded that as electrons.
- His experiment was applied to a hydrogen atom.
- By his model, Thomson concluded that the electrons are present in all the atoms as subatomic particles.
