Question

The Plum pudding atomic model was suggested by Rutherford.

• A. True
• B. False

Answer 1

The correct option is B False

Rutherford's atomic model-

• The Discovery of the nucleus within an atom is attributed to Ernest Rutherford.
• Rutherford performed rays scattering experiment and came to the following conclusions.
• An atom consists of a dense, heavy, positively charged central part called the nucleus, which consists of neutrons and protons.
• The size of the nucleus is very small to that of an atom.
• The electrons are at very large distances from the nucleus.
• There is a large vacant space between the nucleus and electrons.
• The total positive charge on the nucleus is equal to the total negative charge, making an atom electrically neutral.
• The electrons are revolving around the nucleus in circular paths.
• Rutherford's model of the atom is also known as the planetary model of an atom.

Thomson's atomic model-

• In 1904, J.J. Thomson proposed the first model of the atom called the ‘Plum pudding model’.
• According to him, an atom was a spherical cloud of positive charges in which electrons were spread out like plums in a pudding.

Hence, the given statement is false.
