Answer the following
Answers
image ans of 8 no.
Explanation:
6. protons, neutrons, and electrons
7. According to Thomson€™s model of the atom, an atom consists of both negatively and positively charged particles. The negatively charged particles are embedded in the positively charged sphere. ... Thus, by counterbalancing each other€™s effect, they make an atom neutral.
8.
9. The major limitation of Rutherford’s model of the atom is that it does not explain the stability of the atom. As we know now, when charged bodies move in circular motion, they emit radiations. This means that the electrons revolving round the nucleus (as suggested by Rutherford) would lose energy and come closer and closer to nucleus, and a stage will come when they would finally merge into the nucleus. This makes the atom unstable, which is clearly not the case. The electrons do not fall into the nucleus, atoms are very stable and do not collapse on their own.
Answer 3rd
Answer:
1.Sub-atomic particles of an atom are:
(a)Electrons
(b)Protons
(c)Neutrons
2.(a)According to Thomson model, an atom consists of a positively charged sphere and the negatively charged electron are embedded in it.
(b)The negative and positive charges are equal in magnitude. So, the atom as a whole is electrically neutral.
4.Rutherford's model was inadequate to explain the stability of an atom. It did not mention anything about the arrangement of electron in the orbit.
5.True
