Answer:
the production of positive change is equal to negative change
Explanation:
1. On the basis of Thompson’s model of an atom, explain how the atom is neutral as a whole.
Solution:
As per Thompson’s model of an atom,
(i) An atom contains a positively charged sphere in which the negatively charged electrons are implanted.
(ii) Electrons and protons are equal in magnitude, hence an atom on the whole is electrically neutral.
2. On the basis of Rutherford’s model of an atom, which subatomic particle is present in the nucleus of an atom?
Solution:
As per Rutherford’s model of an atom, the positively charged protons are the ones that are present in the atom.
4. What do you think would be the observation if the ∝– particle scattering experiment is carried out using a foil of a metal other than gold?
Solution:
In the ∝ – particle scattering experiment, when any other metal foil is used instead of gold, the observation would remain the same. This is because the structure of an atom when considered individually remains the same.
