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.

Rutherfords experiments lead to the discovery of what?
Earnest Rutherford's experiment,"Gold Foil", led to the discovery the of a Small,dense and positively charged Nucleus
What did Rutherford infer as a result of his observations?
Rutherford Discovered Many key factors of the atom. Especially about Protons and Electrons. He Did Not Know about neutrons. He Concluded That The atoms electron cloud was positive and electron floated around it like chocolate chips in a cookie.
Experiments with gold foil indicated that atoms?
contain a positively charged, dense center
Which observations helped Rutherford determine that atoms have tiny dense positively charged nuclei?
A+ answer: A few of the alpha particles in his expeirment were deflected from the gold foil at large angles. Scattering pattern of alpha particles 'shot' at a thin gold foil. Most went straight thru showing the nucleus was very small. Analysis of the scattering showed electrical repulsion, not that the particles actually hit the nucleus and bounced off.
How was Daltons atomic theory similar to democritus's atomic theory?
It described a nucleus surrounded by a large volume of space.
Which part of a helium atom is positively charged?
nucleus the nucleus contains protons (positive) and neutrons (neutral). The nucleus is always the positively charged, dense center of an atom.
Small dense positively charged nucleus?
Yes.
What is the tiny dense positively charged center of an atom?
Nucleus
Who said there's a small dense positively charged nucleus?
Ernest Rutherford
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.
How can you describe in words ruthfords model of the atom?
the atom as a tiny, dense, positively charged core called a nucleus
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.
Who modeled the atom with electrons that move in fixed circular paths around a dense positively charged nucleus?
Niels Bohr
Which scientist discovered the existence of a center to the atom?
Ernest Rutherford determined that atoms contain a small, dense (not thick), positively charged nucleus.
What scientist concluded the nucleus of an atom contains a dense center of positive charge?
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.
Rutherfords experiments lead to the discovery of what?
Earnest Rutherford's experiment,"Gold Foil", led to the discovery the of a Small,dense and positively charged 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.
