Answers
Answer:
According to Rutherford's model an atom consists of: The centrally located nucleus: The nucleus is a centrally located positively charged mass. The entire mass of the atom is concentrated in it. ... The outer circular orbits: Electrons revolve in circular orbits (shell) in the space available around the nucleus.
Drawback
it couldn't explain the stability of atom
Answer:
answer -AThe model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun.
Explanation:
answer -B The drawback of Rutherford model is:
It can't explain the stability of an atom. As per the model, the orbital revolution of electrons around the nucleus is not stable as the revolving electrons in orbits will undergo acceleration and emit energy. This will result in loss of energy of electrons and they will ultimately fall into the nucleus.
