Question
Which of the following statements were not given by Rutherford model of atom?
- Most of the atom is empty
- Very small fraction of particles is deflected
- Few parts of the particles are bounced back
- Rutherford concluded that electrons are at the center of nucleus.
Hint:
Rutherford concluded that the nucleus is in the center and is surrounded by electrons.
The correct answer is: Rutherford concluded that electrons are at the center of nucleus.
- The planetary model of the atom is proposed by Ernest Rutherford and it is called Rutherford atomic model.
- The model describes the atom as a tiny, dense particle with a positively charged central core called a nucleus.
- The nucleus is surrounded by light and negatively charged particles called electrons which circulate around at some distance.
- The model can be compared with the sun surrounded by the planets.
