Thomson’s plum pudding model explained:a)Electrical neutrality of an atomb)Existence of electronsc)Existence of atomsd)Electrons move in fixed circular orbitsCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Yes ,because acc. to Thompson ,there were same no.of positive and negative parts in an electron

Answer

According this model electron and neutrons are equally distributed over the atom........... And hence positive and negative charge get balance .....ND so atom shows  electrically neutrality ...

Answer

The main features of Thomson’s model of atom are: Atom consists of a positively charged sphere Electrons are embedded in atoms Negative and positive charges are equal in magnitude Atom as a whole is electrically neutral The following diagram illustrates a pictorial representation of the Thomson’s model of atom.      This model was explained with the help of a watermelon wherein the red edible part resembles positive charge in the atom and the black seeds resemble the electrons embedded in positive sphere. This model is also known as plum pudding model as Thomson assumed that atom is a kernel of positive charge which has electrons embedded inside it like seeds in water melon or like raisins in pudding to balance the charge.

Answer

Nuclues is distributed all the parts of watermelon like pulp...and Seeds are electrons....which are distributed equally

Answer

Thomson’s Plum Pudding Model Explained:
Thomson's plum pudding model was proposed in the early 20th century to explain the structure of an atom.

Existence of Electrons:
- In Thomson's model, atoms were thought to be composed of a positively charged sphere with negatively charged electrons embedded within it.
- This model suggested that electrons were distributed uniformly throughout the atom, much like plums in a pudding.

Electrical Neutrality of an Atom:
- One of the key features of Thomson's model was that the overall atom was electrically neutral, with the positive and negative charges balancing each other out.
- This idea helped to explain why atoms did not collapse under the influence of the electrical forces between the charged particles.

Incorrect Options:
- The model does not directly address the existence of atoms (option 'c') as it focuses on the structure of atoms.
- The model also does not suggest that electrons move in fixed circular orbits (option 'd'), as this concept was later proposed by Niels Bohr in his atomic model.
In conclusion, Thomson's plum pudding model is primarily significant for introducing the concept of electrons as constituents of atoms and for proposing a structure that accounted for the electrical neutrality of atoms.
