Who discovered the nucleus using his gold foil experiment?

Ernest Rutherford is the scientist who discovered the nucleus through his gold foil experiment in 1909. He observed that most of the alpha particles passed through the foil, but some were deflected, leading him to propose the existence of a dense, positively charged nucleus at the center of an atom.


Who invented the negatively charged particle electron?

The negatively charged particle electron was discovered by J.J. Thomson in 1897 through his experiments with cathode rays. Thomson's experiments led him to propose the existence of the electron as a fundamental subatomic particle.


How did Rutherford discover atoms?

he didnt discover atomshe discovered the nucleus and electrons thoughhe did this with his gold goil experimenttechnically the first person known to have a therory about atoms was democritus whic was sometime BCEdemocritus' theory was not accepted until sometime in the 1800s by John Dalton who made a very basic modelthen JJ Thompson discovered protons and electronsthen rutherford made his discoveries


Which particular observation of Rutherford do you think him to believe that the atoms is mostly empty space and that its mass is concentrrated in apositve nucleus?

The fact that the vast majority of the alpha particles got straight through led Rutherford to propose that the atom was composed primarily of empty space. The fact that backscattering occurred in 1 in 8000 alpha particles indicated that there was a small massive positively charged nucleus in the centre of the atom.


Who was the first to propose that most of the mass of an atom is in the tiny dense positively charged nucleus?

Greek philosopher Democritus.


How did Rutherford know the nucleus was positively charged?

Rutherford conducted the famous gold foil experiment, where he observed that some alpha particles were deflected back at large angles when they passed through thin gold foil. This led him to propose that the positive charge of an atom is concentrated in a small, dense region called the nucleus.


Did Ernest Rutherford create the mini solar system model an atom?

Yup, by doing the "Gold Foil Experiment" he found that most particles went straight through a sheet of gold foil, while only a very tiny percent was deflected. This meant that the atom was mostly space, it had a tiny solid core called a nucleus, the nucleus is positivley charged and he beleived that the electrons surrounded the nucleus like how planets orbit the sun.


How did Ernest Ruth ford change the atomic model?

Ernest Rutherford's gold foil experiment in 1909 led to the discovery of the atomic nucleus. This helped propose the nuclear model of the atom, in which most of the atom's mass is concentrated in a small, positively charged nucleus at the center with electrons orbiting around it. This work laid the foundation for our modern understanding of the atomic structure.


How did the actual results of rutherfords gold foil experiments differ from the results he expected?

Rutherford expected that the alpha particles would pass through the gold foil with only minor deflections. However, some alpha particles were deflected at large angles, and a few even bounced back. This result led Rutherford to propose the existence of a small, positively charged nucleus at the center of the atom.


In what year did Rutherford propose his atomic model?

1908.


How did J.J. Thomson discover negative charges?

J.J. Thomson discovered negative charges by studying cathode rays in a vacuum tube, where he observed that they were deflected by electric and magnetic fields in a way consistent with negatively charged particles. This led him to propose the existence of negatively charged particles, which he later named electrons.


What was Rutherford trying to prove with his experiment?

Rutherford's experiment aimed to investigate the structure of atoms by studying the deflection of alpha particles as they passed through a thin gold foil. By observing the pattern of deflected particles, he aimed to understand the distribution of positive charge within the atom and propose the existence of a dense, positively charged nucleus at the center. This experiment ultimately led to the development of the nuclear model of the atom.
