How did Ernest Rutherford make a contribution to the development of the atom?
Rutherford shot subatomic alpha peticles (radiation) at gold foil and realized that most of the particles passed through the gold without interacting with it. This led to a revolutionary idea that atoms are mostly empty space and created the model of a nucleus surrounded by, but not connected to, it's electrons. An analogy I sometimes use is the idea of shooting BB's at a solid wall or at a chain link fence. None will pass through the wall but most will go right through the fence without ever touching it.
When neutrons were discovered were these neutrons created in the experiments?
Neutrons were discovered through experiments involving bombarding beryllium with alpha particles. Neutrons were not created in these experiments, but were instead found as subatomic particles that make up the nucleus of atoms.
What important discovery did Alexander Flemming make in 1928?
Alexander Fleming discovered penicillin, the first antibiotic that revolutionized the treatment of bacterial infections in medicine. This discovery laid the foundation for the development of many other antibiotics and significantly improved the survival rates of patients with bacterial diseases.
What did democritus and Dalton and Thomson and Rutherford and bohr contribute?
Democritus proposed the concept of atoms as indivisible particles that make up all matter. Dalton developed the atomic theory, stating that elements are composed of indivisible atoms with specific properties. Thomson discovered the electron and proposed the "plum pudding" model of the atom. Rutherford conducted the gold foil experiment, leading to the discovery of the atomic nucleus. Bohr introduced the planetary model of the atom, with electrons orbiting the nucleus in specific energy levels.
Who discovered each particle of the atom?
The electron was discovered by J.J. Thompson. Simply, he used a Cathode ray tube and magnetic fields to "bent" the flow of particles. He also determined the mass to charge ratio of the electron, thus proving it to be less massive (and a component) of the atom. By extension, as electrons were negative and matter is generally neutral, he knew that there must be something positive inside the atom to balance the charge. He came up with the plumb pudding model of the atom. The proton was discovered by Ernest Rutherford. He bombarded a sheet of gold foil with alpha particles, and found that the majority of these particles passed through (thus disproving the plumb pudding model) while very few were radically deflected or reflected. The neutron was discovered by James Chadwick. His experiment was a variation on that used by Irene Curie and her husband involving polonium and alpha radiation. The discovery of each of the three basic particles that make up the atom is take up by three separate questions - one for each one. All there questions are listed in the related questions area below, and they are links to those questions.
How did ernest Rutherford make a difference in the world you live in?
Ernest Rutherford was a New Zealand-born British physicist who became known as the father of nuclear physics. He discovered the nucleus of the atom in 1911.
Which two scientist discovered particles that make up the nucleus?
Ernest Rutherford and his team conducted the gold foil experiment, which led to the discovery of the positively charged nucleus in atoms. James Chadwick then discovered the neutron as a neutral particle within the nucleus.
What Discoveries Did Ernest Rutherford Make?
electron or atoms I believe, taking up space
Which two scientists discovered the subatomic particles that make up the nucleus?
Ernest Rutherford and James Chadwick were the scientists who discovered the subatomic particles that make up the nucleus. Rutherford discovered the positively charged protons, while Chadwick discovered the uncharged neutrons.
What contribution did Ernest Rutherford make to the atomic energy?
he practically discovered the neutron which then some scientist came out with something called fission
What year did ernest Rutherford make a contribution to the atomic model?
He didn't exactly "discover" the nucleus. In 1911 he theorized about the atom having its positive charges in a very small nucleus. In 1921 he postulated about the existence of the neutron in the nucleus. The first experiment to split the atom in a controlled manner was performed by him and two students in 1932.
What important discovery did Columbus make?
that the earth is round
How did ernest Rutherford make the nuclear bomb?
Ernest Rutherford did not make the nuclear bomb. He was a physicist who conducted pioneering work in the field of nuclear physics, particularly on the structure of the atom. The development of the nuclear bomb was primarily led by other scientists during the Manhattan Project in World War II.
What important discovery did Manson make?
He found the cure for cancer :)
What important exploration or discovery did the vikings make?
they discovered the first way of purifying water
What is significant about Ernest Rutherford?
Rutherford came up with the basic structure of an atom using his gold foil experiment. He shot alpha particles(hydrogen nuclei) at a peice of gold foil and watched the results. He found from this experiment that the atom contains a dense, positively charged nucleus, negative particles in "electron clouds" and is made up of mostly empty space.
Why was the discovery bronze important to the early civilizations?
Bronze could be used to make stronger tools and weapons.
