Question

1. Rutherford performed the experiment for atomic model using_______ particle a. beta particle b) alpha particle c) electron d) proton ​

Answer 1

Answer:

alpha particles

Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure. If Thomson was correct, the beam would go straight through the gold foil. Most of the beams went through the foil, but a few were deflected.

Explanation:

Answer 2

Rutherford performed the experiment for the atomic model using alpha particles. (option b)

• He beamed the alpha particles through a gold foil, observing that most of the particles traveled straight through the foil while some particles got deflected.
• He concluded from the gold-foil experiment that, atoms have a tiny, dense positively charged core known as the nucleus and it is surrounded by light, negatively charged bodies called the electrons.
• The nucleus forms the center while the electrons orbit the nucleus. The nucleus was responsible for the scattering of alpha particles away from the gold foil.
• This came to be known as the Rutherford atomic model, nuclear atom or planetary model of the atom.
