Question

Practical to determine specific charge of an electron by thomson method

Answer 1

Explanation:

The atomic model was proposed by J.J.THOMSON in 1898. This model was commonly called the PLUM PUDDING MODEL,referring to the way the fruit pieces are distributed throughout a plum pudding.

• An atom is considered to be a sphere of uniform positive charge and electrons are embedded in it.
• The total mass of the atom is considered to be uniformly distributed through out the atom
• The negative and positive charges are supposed to balance out and the atom as a whole is electrically neutral.

The red part of water melon is positive charge and black seeds are negative charge as he considered

Answer 2

In Thomson's model, the atom is composed of electrons surrounded by a soup of positive charge to balance the electrons' negative charges, like negatively charged “plums” surrounded by positively charged “pudding”.
