Question

which scientists research led to the construction of the atomic model shown?
electrons
alpha particle
paths
nucleus
a) bohr
b) chadwick
c) thomson
d) rutherford

Explanation:

• Bohr: Proposed a model where electrons orbit the nucleus in fixed energy levels.
• Chadwick: Discovered the neutron.
• Thomson: Proposed the "plum - pudding" model (electrons embedded in a positive "soup").
• Rutherford: Conducted the gold - foil experiment. Based on the alpha - particle scattering results (some alpha particles were deflected at large angles), he proposed the nuclear model of the atom (a small, dense, positively - charged nucleus with electrons outside). The given model (with a nucleus and electrons, and alpha - particle paths) is Rutherford's nuclear model.

Answer:

D. Rutherford
