Question

(a)What was Thomson's model of an atom?
(b)write any two observations of Rutherford's model of an atom.​

Answer 1

Answer:

a) electron is the answer hope it will help u

Answer 2

Answer:

(a) In 1897, J.J. ... In 1904, Thomson proposed atomic model where electrons are embedded within spherically distributed, positive charge (so-called "plum pudding" model). Both the positive charge and the mass of the atom would be more or less uniformly distributed over its size.

(b)Observation of Rutherford's model of an atom:

1. Observation of Rutherford's model of an atom:Major space in an atom is empty.
2. Observation of Rutherford's model of an atom:Major space in an atom is empty. A large fraction of α-particles passed through the gold sheet without getting deflected.
3. Observation of Rutherford's model of an atom:Major space in an atom is empty. A large fraction of α-particles passed through the gold sheet without getting deflected. Very few α-particles had deflected at large angles or deflected back. Moreover, very few particles had deflected at 180degrees. .
