Ernest Rutherford discovered that atoms have a very dense nucleus, which contains protons.
Rutherford eventually coined the terms for some of the most basic principles in the field: alpha, beta, and gamma rays, the proton, the neutron, half-life, and daughter atoms
he found that all known radioactive elements emit two kinds of radiation: positively and negatively charged, or alpha and beta. He showed that every radioactive element decreases in radioactivity over a unique and regular time, or half-life, ultimately becoming stable.
He discovered the atomic nucleus and developed a http://wiki.answers.com/dp13at.htmlelof the atom that was similar to the solar system.
Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly the same consistency throughout, with negatively-charged electrons scattered about in it like raisins in a pudding. As part of an experiment with x-rays in 1909, Rutherford was shooting a beam of alpha particles (or alpha rays, emitted by the radioactive element radium) at a sheet of gold foil only 1/3000 of an inch thick, and tracing the particles' paths. Most of the particles went right through the foil, which would be expected if the atoms in the gold were like a plum pudding. But every now and then, a particle bounced back as though it had hit something solid. After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all its mass, and positive charge, in a central nucleus about 10,000 times smaller than the atom itself. All of the negative charge was held in the electrons, which must orbit the dense nucleus like planets around the sun.
He was the New Zealand physicist who split the atom
From: Bradwell Institute Information
In 1911, he suggested that atoms have their positive charge concentrated in a very small nucleus, and pioneering with the Rutherford model, through his discovery and interpretation of Coulomb scattering in his gold foil experiment. He is widely credited with first splitting the atom in 1917.
He is known for the "Rutherford Model," which says that positive atoms are inside a nucleus. He split and atom and studied nuclear physics, which has advanced the science world (hence the reason he is famous).

Rutherford discovered that protons are concentrated at the center of an atom when he fired alpha particles at a thin metal foil and had them bounce back. He said it was as if "you had fired a 15-inch naval shell at a piece of tissue paper and the shell came right back and hit you".
Rutherford also named and characterized alpha and beta radiation, and showed how an element changes when it experiences radioactive decay.
Rutherford was more famous among his peers for his research in radio-waves. His experiments were the first to investigate "wireless" communication, years before the pioneers in the industry. The room used for his experiments is now a memorial, dedicated to the radio-wave research.

Ernest Rutherford proved it with his famous gold foil experiment.
Ernest Rutherford invented names to classify various forms of of rays. There were/are such words as 'alpha', 'beta' and 'gamma rays'. He split the atom and invented corrugated iron.
The short answer is that Ernest Rutherford discovered the nucleus of the atom and was a mentor to Niels Bohr who further refined the model by showing that the nucleus was made up of neutrons and protons. The existence of electrons had already been inferred earlier. Ernest Rutherford opened the door to the field of nuclear physics whereas Niels Bohr's contributions pointed the way to quantum physics. At the time, it was noted that the nucleus within the atom takes up about as much space as a fly in a cathedral. Since then, it has been shown that the subatomic particles are themselves made up mostly of vast empty spaces containing tiny specs of something that may be described as either energy or matter or neither and both.
Rutherford's experimenters were Hans Geiger, and Ernest Marsden, both of whom went on to have worthwhile science careers. The metal foil used in the Rutherford experiments was gold, for this foil amy be made extremely thin by careful beating, whilst still being imperforate.
They were never invented. They were discovered by various people at various times: Ernest Rutherford effectively discovered protons, around 1910, with his famous gold film experiment. He is usually "officially" credited with the discovery for his work in 1919. The electron was discovered in 1897 by J.J. Thomson. The neutron was discovered in 1932 by James Chadwick.

Rutherford was a famous Russian scientist who discovered nucleus in chemistry. his full name was lord ernest Rutherford
Sir edmund Hillary Kate Sheppard ernest rutherford
In the early period of the 1900s, Ernest Rutherford became famous for his discovery of the nucleus. He was an English physicist.
Ernest Rutherford concluded that an atom contains a very small, dense center, called a nucleus, with a positive charge as a result of his gold foil experiment.
Ernest Rutherford, with students Ernest Marsdenand Hans Geiger, in the 'gold foil' experiment, demonstrated the existence of the atomic nucleus.
After that famous experiment, it was realized that atoms were mostly empty space.
Ernest Rutherford proved it with his famous gold foil experiment.
Ernest Rutherford suggested that most of the mass of the atom is located in the nucleus. He came to this conclusion after finding the results on his famous gold foil experiment. This is where he fired radio active particles through very thin metal foils, and detected them using screens covered in zinc sulphide.
