Q.3.Which of the following properties of atom could be explained correctly by Thomson Model
of atom?
(i)Overall neutrality of atom.
(ii)Spectra of hydrogen atom.
(iii)Position of electrons, protons and neutrons in atom.
(iv)Stability of atom.
Answers
Answer:
(i)
Explanation:
According to Thomson model of an atom:
1. An atom has spherical shape with radius ≈10
–10
m.
2. The positive charge is uniformly distributed in the atom.
3. The electrons are embedded such that atom posses the most stable electrostatic arrangement.
Thereby the model was able to explain the overall neutrality of the atom.
4. the mass of the atom is assumed to be uniformly distributed over the atom.
It could not explain the atomic spectra, stability of the atom and the actual distribution of electrons, protons and neutrons in the atom.
