outline rutherford's contribution to understand the nucleus of an atom
Answers
Answer:
Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure
The Rutherford's model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun. According to the model electron’s speed will keep reducing as the electron keeps giving off energy by emitting EM waves and the radius of its rotation will keep decreasing and it will soon crash into the nucleus.
