He concluded that most of the mass of the mass of the atom is concentrated at a single place at the centre of atom. He named this place as the nucleus.

Who discovered the nucleus using his gold foil experiment?
Rutherford by bombarding gold foil with positively charged particles and noting that some particles were widely deflected.
How does the particles of matter react to temperature?
It is widely accepted within the scientific field that higher levels of heat to cause particles to move more quickly. An air molecule, for example, will be moving much faster at higher temperatures than it would at lower temperatures.
State of matter containing most widely separated particles?
Possibly interstellar gas comes close to your need. GAS is the state of matter with the greatest Disorder
What is an example of compressional waves?
a slinky spread out and then grab a few coils and release and watch a compressional wave! Another example is a sound wave. the particles compressed together form a compression. The particles more widely spread apart form a rarefaction.slinkySound waveCompressional waves are also called mechanical waves. Examples include the plasma waves or guided waves.
Why cgs and mks is widely used?
CGS is NOT widely used. It was in the past. The only system of measurement that is widely used today is the SI, which is a variety of MKS.

Who identified atoms had a positive nucleus with widely spaced electrons?
Rutherford is the one who experimented the internal structure of atoms by shooting alpha particles on a slim pieace of gold. he realised that most of Alpha particles gets through it, some of them deviates and the few rest bounce back. He concluded that the atom is consisted from empty space, and in its center lies a neculeus that resuls in bouncing back some of the particles and that this nucleus is positive to explain the deviation.
What is an area of crowded particles followed by widely spaced particles?
An area of crowded particles followed by widely spaced particles is known as a density wave. In a density wave, particles are closely packed together in one region, creating a dense area, and then spread out and become less concentrated in another region, resulting in a sparse area. This pattern repeats periodically, forming a wave-like structure.
What evidence is there that the nucleus of an atom is very small and positively charged?
Rutherford's famous gold foil and proton experiment showed that very occasionally a proton fired at a nucleus came straight back at the 'gun'. He likened it to a naval shell being returned after hitting a piece of tissue paper. The fact that so few protons returned or were deflected by the tiny nucleus compared to the billions emitted by the proton 'alpha' source showed that nuclei of gold atoms were small and very widely spaced apart.
Who is famous scientist and why is the famous?
well, there's Albert Einstein and he was famous for creating the atom bomb and plenty of other things. And Earnest Rutherford Rutherford performed his most famous work after he received the nobel prize for chemistry. In 1911, he postulated that atoms have their positive charge concentrated in a very small nucleus, and thereby pioneered the Rutherford model, or planetary, model of the atom. He is widely credited with first splitting the atom in 1917.
What year did ernest Rutherford split the atom?
Rutherford and his team investigated the structure of matter using natural radioactivity and discovered that atoms have a nucleus with positive charge. Rutherford put forward a model of the atom to explain the things his team found in their experiments, and this was an important step in our understanding of atomic structure. The work continued and resulted in the first nuclear reactions. Although Cockroft and Walton actually split the atom, the procedure derived from Rutherford's work. The object of all these experiments was to understand the structure of matter.

What state matter has particles flying about wildly?
Particles in a gas are not connected and move freely.
State of matter containing most widely separated particles?
Possibly interstellar gas comes close to your need. GAS is the state of matter with the greatest Disorder

Rutherford performed a famous experiment at Manchester University in which he fired alpha particles (the nucleus of a helium atom) at a very thin piece of gold foil in order to probe the structure of the atom. Before this experiment the "pudding plumb" model of the atom was widely accepted; which was a rather large nucleus (the plumb) surrounded by a soup of electrons that where evenly distributed (the pudding). When Rutherford performed his experiment he discovered something quite different, which was that most of the atom is just empty space with a very small, but very dense, nucleus surrounded by tiny electrons (relative to the nucleus). This was the first experiment performed that reviled the structure of the atom as we know it today.
Ernest Rutherford Did he become famous straightaway?
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 atomshe 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 atomFrom: Bradwell Institute Information
