Question

ASSERTION: Thomson's atomic model is known as raisin pudding model. REASON,:The atom is visualised as a pudding of positive charge with electrons( raisins) embedded in it. *

Both A and R are true and R is the correct explanation of A.

Both A and R are true but R is not the correct explanation of A.

A is true but R is false.

A is false but R is true​

Answer 1

ANSWER :

• Thomson's model of atom is also known as water-melon model, raisin pudding model and plum pudding model. The representation of the atom in Thomson's model represents a pudding and a watermelon.

A is true but R is false

Answer 2

Thomson's atomic model is called the raisin pudding model, the reason for this is that according to him, an atom are positively charged particles with negatively charged, raisin like spheres embedded in it. Hence, both, the assertion(A) is true and the statement(R) is the correct explanation for it.

• Before the advent of modern technology, there were several attempts made by prominent scientists of what exactly an atom consists of
• One such atomic model was that of scientist J.J. Thomson. He is the individual credited with the discovery of the electron, using a cathode ray tube
• These models attempted to explain the size, stability, and functions of an atom based on the principles and understandings of their time
