What did Rutherford discover about atom structure?
Rutherford oversaw the gold foil experiment. This experiment showed that the atom is mostly empty space and that most of its mass is concentrated in a tiny central core called the atomic nucleus.
What was Ernest Rutherford's biggest contribution to chemistry?
In 1911, Rutherford proposed a new model for the atom. His experiments were the first to show that the atom must consist of a very tiny positively charged nucleus surrounded by negatively charged electrons. (For the record, Rutherford also discovered and named alpha, beta and gamma radiation.)
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.
What is the explanation for the scattering experiment of Rutherford?
Rutherford conducted an experiment in which Alpha particles were fired at a gold nucleus. Most of the particles passed through unaffected. However, some were deflected by a small amount whilst an even smaller number of the particles were deflected completely. This led to the conclusion that the atom has an extremely small, central, positively charged nucleus. As both the positive alpha particle and the positive nucleus repel each other by electrostatic forces. The fact that only a small amount of particles are deflected shows that the nucleus is only a tiny central part of the atom.
Is the nucleus of an atom small or big?
Tiny.
Who is the scientist that discovered the nucleus?
Actually Ruthford discovered the Nucleus
What did ernest rutherford conclude about the nucleus of an atom?
Rutherford claimed that at the center of an atom there was a very tiny, very dense, positively charged part called a nucleus, surrounded by electrons at a distance.
What is the difference between the models made by Rutherford and Dalton?
Dalton's atomic model simply stated that all elements were made of tiny atoms, he said nothing about the structure of those atoms. Rutherford proposed that most of the mass of the atom is concentrated in a tiny central nucleus with positive charge.
What did Rutherford add to the atomic model?
He discovered that an atom has a very dense and very tiny positively charged nucleus. He named the positively charged particles protons.
What discoveries about the atom did Rutherford make from Hus teams experiments?
He discovered that an atom's positive charge must be clustered in a tiny region in its center, the nucleus

What scientist said most of the mass of the atom is in tiny dense positively charged nucleus?
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.
What is the contribution of a foriegn scientist?
Ernest Rutherford was the first person to transmute an element. He also produced the model of an atom in which a tiny nucleus was surrounded by a vast space in which the electrons moved.

Why did Rutherford infer that most of the mass and all the positive charge in the atom is in a tiny nucleus?
He decided upon this conclusion because when he put a thin sheet of foil and got some atomic bullets and fired them at it, most of the bullets just went straight through because there was nothing stopping them. but a few were deflected and so he decided that the bits where the bullets were deflected must hold all the mass of the Atom.
