Describe an experiment that led to the discovery of nucleus of an atom.
Answers
Answer:
the rutherford gold foil experiment offered the first experimental evidence led to the discovery of the nucleus of atom as a small dense and positive charged atomic core. With Gaiger and Marsdense experi.ental evidence Rutherford deduced the model of the atom discovering the atomoc nucleus
Answer:
J.J. Thomson and the discovery of the electron
In the late 19th, start superscript, start text, t, h, end text, end superscript century, physicist J.J. Thomson began experimenting with cathode ray tubes. Cathode ray tubes are sealed glass tubes from which most of the air has been evacuated. A high voltage is applied across two electrodes at one end of the tube, which causes a beam of particles to flow from the cathode (the negatively-charged electrode) to the anode (the positively-charged electrode). The tubes are called cathode ray tubes because the particle beam or "cathode ray" originates at the cathode. The ray can be detected by painting a material known as phosphors onto the far end of the tube beyond the anode. The phosphors spark, or emit light, when impacted by the cathode ray.
